Domain and Scope Calculator: The Complete Analysis (2023)

Functions are an extremely important part of mathematics and physics. In the context of functions, domain and range are two topics that we need to discuss. The area and area calculator calculates the area and the area of ​​a given function.

For a function y = f(x),

A domain is defined as the set of possible values ​​"x" of a function that results in the value "y". It is the set of possible values ​​for the independent variables. The scope of a function is defined as the set of values ​​resulting from the dependent variable. These are the output values ​​when the values ​​of x are substituted. It is similar that when the input values ​​are passed to the function, the function produces the output.

In short, a domain is defined as the set of values ​​for which the function f(x) is defined, while the range is defined as the set of values ​​that the function assumes. The domain is called the substitution set and the domain is called the solution set.

Domain and Range Calculator Graph:

However, it is simply not enough to calculate the domain and range of a function. Often we need to follow this process by graphing the function. Here we use its domain and image values ​​to represent it.

In fact, this process is quite simple. We plot the x-values ​​on the horizontal axis and the y-values ​​on the vertical axis.

First we need to graph the y-values ​​that we get from the function that correspond to any value of x.

We then connect these points to form the graph of the function.

The same task can also be accomplished using an online calculator. In that case, just paste the function in the space provided. Then click the Calculate Input button. The graph for that specific function is displayed. Also, we provide the link to access this calculator to facilitate the whole process of drawing the diagram:

Domain and area calculators with points:

You can also find the domain and range if you have a set of points instead of a function. In fact, it may seem surprising at first, but it is true.

To reiterate what we said before, the points are simply coordinates.

For example, imagine a coordinate of the form (x, y).

The value of x can be any number, and the value of y is the value of the function for each corresponding value of x.

In other words, x and y are the domain and range of the function. Since x can be any value and the value of y depends on the value of x, you can understand that the last statement is true.

For any given set of points of a function (a,b), (c,d), (e,f) and (g,h), say

The domain of the function is: {a, c, e, g} e,

The range of this function is: {b, d, f, h}.

Obviously, given its coordinates, we can easily calculate the domain and range of the function.

Domain and scope of a function:

In the previous sections, we have provided you with many domains and reach calculators. Now let's discuss the concepts of domain and range in detail.

ODomainA function is the complete set of possible values ​​of the independent variable.

In plain language, this definition means:

The domain is the set of all possibleX-Values ​​that make the function "work" and produce in real termsj-Values.

However, there are also two points to keep in mind:

• The denominator of a fractional function cannot be negative.
• Also, in this context, the term under a square root must not be negative.

OAreaof a function is the set of its possible output values.

Domain and range of values ​​of a modulo function:

The value of the modulo function is always nonnegative. If f(x) is a modular function, then:

That is, if the value of x is greater than or equal to 0, the modulo function takes the real value, but if x is less than 0, the function takes "x" minus the real value.

We can apply the modulus function to any real number. The domain of the modular function is the set of non-negative real numbers, denoted as (0,∞), and the domain of the modular function is R (where R refers to the set of all positive real numbers). Therefore, the domain of definition is the function moduloRand the range is (0,∞).

Now let's see how to draw the graph for a modulo function. Let us consider x as a variable with values ​​from -5 to 5. When calculating the modulus for positive values ​​of 'x' the line drawn on the diagram is 'y = x' and for negative values ​​of 'x' ' the line drawn on the plotted line of the graph is 'y = -x'.

The graph of the modulo function looks like this:

Domain and range of trigonometric functions:

ODomain and range of trigonometric functionsthey are given by the angle θ and the resulting value, respectively. The domain of trigonometric functions are angles in degrees or radians, and the amplitude is a real number. Some values ​​are excluded from the domain and range of trigonometric functions, depending on the region where the trigonometric function is undefined.

The range of trigonometric functions denotes the values ​​of the angles at which the trigonometric functions are defined, and the range of trigonometric functions denotes the resulting value of the trigonometric function that corresponds to a specific angle in the range. There are three main trigonometric functions: sin θ, cos θ, and tan θ.

The other three trigonometric functions are sec θ, cosec θ and cot θ.

For example, the domain and area of ​​the sine are:

We know that the sine function is the ratio between the perpendicular and the hypotenuse of a right triangle. Then the domain and range of the trigonometric function are sine:

• domain = all real numbers, that is, (−∞, ∞)
• range = [-1, 1].

For example, the domain and range of cosine are:

We know that the cosine function is the ratio of the side adjacent to the hypotenuse of a right triangle. The domain and range of the cosine trigonometric function are:

• domain = all real numbers, that is, (−∞, ∞)
• range = [-1, 1].

The defining domain and the tangent area are, for example:

We know that the tangent function is the ratio of the opposite and adjacent sides of a right triangle. Tan is the quotient of the sine and cosine functions, so the domain of tan x does not include values ​​where cos x is zero.

Therefore, the domain and the area of ​​the tangent of the trigonometric function are:

• Domain = R - (2n + 1)π/2
• area = (−∞, ∞).

Examples of domain and range:

Example 1:

Find the domain of f(x) = 5x − 3

Solution

The domain of a linear function is all real numbers, so

Domain: (−∞, ∞)

Range: (−∞, ∞)

Example 2:

Find the domain of the function f(x)=−2x²+ 12x + 5

Solution

The function f(x) = −2x²+ 12x + 5 is a quadratic polynomial, so the domain is (−∞, ∞).

Example 3:

Find the domain of x−4/(x²−2x−15)

Solution

Set the denominator to zero and solve for x

⟹x²− 2x – 15 = (x − 5) (x + 3) = 0

Also x = −3, x = 5.

To prevent the denominator from being zero, we must avoid the numbers -3 and 5. So the domain consists of all real numbers except -3 and 5.

Example 4:

Find the domain and range of the function f(x) = -2/x.

Solution

Set the denominator to zero.

⟹ x = 0

Then domain of definition: All real numbers except 0.

The range includes all real values ​​of x except 0.

Here are a few more to practice:
