Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable. A steeper slope means a greater rate of change.

Front

How do you determine which function grows faster?

Back

To determine which function grows faster, compare their slopes. The function with the larger slope increases more rapidly.

Front

How do you calculate the difference in commissions between two people?

Back

To calculate the difference in commissions, subtract the total commission of one person from the total commission of the other.

Front

What does it mean if two functions intersect on a graph?

Back

If two functions intersect on a graph, it means they have the same value (output) at that point for the same input (x value).

What is the formula to find the total steps taken by Elyse in 3 hours if she walks 575 steps in the first hour?

Back

Elyse's total steps in 3 hours = 575 + 1150 + 1725 = 3450 steps.
