The video tutorial explains how to calculate the average rate of change of a function y of x over a given interval. It starts by identifying the initial and final values of x and y, then introduces the concept of delta notation to represent changes. The tutorial walks through the steps to calculate the average rate of change, emphasizing the change in y over the change in x, and concludes with the final result.

What is the interval over which the average rate of change is calculated?

• From -5 to -2

• From -2 to 5

• From 6 to 0

• From 0 to 6
