This was what google give me lol.

The functions in order from least to greatest according to their average rates of change are function f at the interval [1,2], function h at the interval [0,2] and function g at the interval [2,3]
<h3>How to order the functions?</h3>
The rate of change is calculated using:

For function g at the interval [2,3], we have:

This gives


For function h at the interval [0,2], we have:

Where:
h(2) = 3(3)^2 - 9 = 18
h(0) = 3(3)^0 - 9 = -6
This gives


For function f at the interval [1,2], we have:

This gives


Hence, the functions are function f at the interval [1,2], function h at the interval [0,2] and function g at the interval [2,3]
