Average Rate of Change

Front

What is the Average Rate of Change (ARC)?

Back

The Average Rate of Change is a measure of how much a quantity changes on average over a specific interval. It is calculated as the change in the value of a function divided by the change in the input value.

How do you calculate the Average Rate of Change between two points?

Back

To calculate the Average Rate of Change between two points (x1, y1) and (x2, y2), use the formula: ARC = (y2 - y1) / (x2 - x1).

What does it mean if the Average Rate of Change is undefined?

Back

An undefined Average Rate of Change indicates that the x-values are the same, which means the slope of the line is vertical.
