find the average of change of function g(x) from x=-1 to x=2

To find the average rate of change of a function g(x) over a given interval [a, b], we can use the following formula:

Average rate of change = [g(b) - g(a)] / (b - a)

Given that the function g(x) is not provided, we cannot calculate the average rate of change without knowing the actual function or a specific expression for g(x) between x = -1 and x = 2. If you provide the function g(x), we can help you find the average rate of change over the interval x = [-1, 2].
