Question

Given the function defined in the table below, find the average rate of change, in simplest form, of the function over the interval

4
≤
x
≤
6
4≤x≤6.

Answer 1

Substitute 4 and 6, separately, into the function for x. Then use the average rate of change equation, change in y/ change in x, or y1-y2/x1-x2, or f(4)-f(6)/4-6.
