APPC Unit 1 Review: Exploring Rates of Change (CED: 1.1-1.6)

Lala's math class had an exam, where grades were between 0 and 10. Let N(g) denote the number of students whose grade was g. Interpret N(k) = 7

• The value of the unknown, k , is equal to 7

• There are k students whose grade on the exam was 7

• There are 7 students whose grade on the exam was k

• The average rate of change of the linear function N(k) = 7

The chart displays the sales of a certain Company, A.

• The graph of the sales data could be concave up because the rate of change is increasing over consecutive equal length intervals

• The graph of the sales data could be concave down because the rate of change is increasing over consecutive equal length intervals

• The graph of the sales data could be concave down because the rate of change is increasing over consecutive equal length intervals

• The graph of the sales data could be concave down because the rate of change is decreasing over consecutive equal length intervals
