Based on the graphs of f(x) and g(x) below, answer the following questions. You should not approximate any of your answers.
a) What is the average rate of change of f(x) over the interval 2.2≤x≤8 ?
b) What is the average rate of change of g(x) over the interval 2.2≤x≤6.1 ?

Don't you think the slope will be same then? D:

it says average rate of change so drawing straight line gives u average
