Unit 2 Lesson 1 - Determining Average Rate of Change

Fill in the blank: ______________ ROC = dependent variable is decreasing over the interval.

• Rate of Change

• Rate of Climb

• Rate of Cost

• Rate of Consumption

Average Rate of Change = change that takes place across an _________________

• interval

• equation

• point

• function

Linear = provides a ________________ for all intervals → ___________

• Linear function

• Exponential function

• Quadratic function

• Logarithmic function

Non-Linear = provides a ___________________ at different intervals

• Non-Linear = provides a function at different intervals

• Non-Linear = provides a constant at different intervals

• Non-Linear = provides a straight line at different intervals

• Non-Linear = provides a uniform distribution at different intervals

Use the slope formula to calculate the AROC for the secant line that connects the two points. The table below shows the number of copies of a new video game sold by an electronics store each week for the first month after the game’s release. What is the average rate of change in the number of copies sold from Week 1 to Week 4?

• 100 copies per week

• 150 copies per week

• -32 copies per week

• 250 copies per week

• 2

• 4

• 6

• 8
