Learn how evaluate the an absolute value function

The video tutorial covers evaluating functions, focusing on finding the value of a function at specific intervals. The example used is the absolute value function, where the value is calculated at the interval of -3. The process involves substituting the input value into the function, performing arithmetic operations, and applying the absolute value to find the result. The tutorial emphasizes the importance of understanding the steps involved in evaluating functions.

What is the primary goal when evaluating functions at specific intervals?

• To graph the function

• To find the value of the function at those intervals

• To change the function's formula

• To determine the slope of the function

When substituting a value into a function, what is the first step?

• Solve the equation for x

• Graph the function

• Replace the variable with the given value

• Find the derivative of the function

In the example given, what value is substituted into the function?

• 3

• -3

• 1

• 0

What is the absolute value of -10?

• 10

• 20

• 0
