Comparing Functions and Rates of Change

The video tutorial explains how to compare equations and verbal descriptions by analyzing their function properties. It introduces the concept of verbal descriptions as a way to represent functions and compares them with algebraic equations using real-world examples. The tutorial highlights common mistakes and clarifies the correct interpretation of inputs and outputs. It also discusses the constant rate of change and how to identify it in both equations and verbal descriptions. The lesson concludes with additional examples to reinforce the learning objectives.

What is the main focus of the lesson introduced at the beginning?

• How to solve complex equations

• How to compare two functions using equations and verbal descriptions

• How to graph functions

• How to calculate the area of a circle

Which of the following is NOT a representation of a function?

• Algebraic

• Numeric

• Graphic

• Geometric

In the example of selling programs, what is the correct equation for the total cost?

• y = x + 2

• y = 2x

• y = x - 2

• y = 2 + x

What is the constant rate of change in Frank's lunch card example?

• -2.00

• -1.25

• 2.00

• 1.25

Why is the rate of change negative in Frank's lunch card example?

• Because the card is faulty

• Because the lunch is free

• Because he is adding money to the card

• Because he is spending money on lunch
