When dealing with a function, it is important to understand the concept of its domain and range. The domain of a function refers to the set of all possible values of the independent variable x, while the range refers to the set of all possible values of the dependent variable y. The domain and range of a function can be determined by using an inequality.

## What Is an Inequality?

An inequality is a mathematical expression that states two values are not equal. It is used to determine a set of values for which certain conditions are satisfied. In order to find the domain and range of a function, an inequality must be used to determine the set of values that form the solution to the equation.

## How Does an Inequality Work?

An inequality is a mathematical statement that shows how two values are related. It can be used to give an idea of how two variables are related. For example, the inequality x > 3 indicates that for any value of x that is greater than 3, the corresponding value of the function f(x) will also be greater than 3. Similarly, if x is less than 3, the corresponding value of the function f(x) will also be less than 3.

## How Is an Inequality Used to Find the Domain and Range of a Function?

To find the domain and range of a function, an inequality can be used to identify the set of values that form the solution to the equation. In the case of Mc015-1.Jpg, the inequality x ≤ 0 can be used to determine the domain of the function f(x). This means that for any value of x less than or equal to 0, the corresponding value of the function f(x) will also be less than or equal to 0.

## Conclusion

An inequality can be used to determine the domain and range of a function. In the case of Mc015-1.Jpg, the inequality x ≤ 0 can be used to identify the set of values that form the solution to the equation. By understanding the relationship between the variables x and y, an inequality can be used to determine the domain and range of the function f(x).
