Learn how to evaluate for a function

The video tutorial explains how to evaluate functions, focusing on two functions, F and G. It covers the basic concepts of function evaluation, including inputs, outputs, and rules. The tutorial demonstrates evaluating function F at a specific input, showing the calculation process. It then moves on to function G, explaining how to combine terms and apply the distributive property to find the function's value. The tutorial aims to help viewers understand the steps involved in evaluating functions and the importance of correctly substituting inputs.

What is the role of 'X' in a function?

• The constant in the function

• The input value for the function

• The output of the function

• The name of the function

If F(x) = 3x - 1, what is F(-3)?

• 9

• 7

• 10

• 8

What is the first step in evaluating G(x) = x + 2x - 1?

• Subtract 1 from x

• Plug in the value of x

• Combine like terms

• Apply the distributive property

What is the simplified form of G(x) = x + 2x - 1?

• 3x - 1

• 2x + 1

• x - 1

• x^2 - 1

How do you evaluate a function at a specific input?

• Add the input value to the function

• Multiply the function by the input value

• Replace the input variable with the specific value

• Replace the function name with the input
