when you evaluate a function, it means that you are going to solve for the function value given a particular value of the _________ used in the equation.

Evaluating function is the process of evaluating the function at the value assigned to a given variable.

## Evaluating Functions

Finding the value of f(x) =… or y =… that corresponds to a given value of x is known as evaluating a function. Simply replace all of the x variables with whatever value has been provided to x. When we are asked to assess f(2), for example, we are given the number 2 for x.

**Example:**

Example: Given that f(x) = 3x - 2, find f(4)

**Solution:** We will evaluate the function once the value of x has been set to 4. The first step is to change each x to a 4. Then, using the order of operations, evaluate the function.

f(x) = 3x - 2

x=4,

f(4)=3.4-2

f(4)=12-2

f(4)=10
