Answer 1

I can’t see the graph you mentioned. The average rate of change of f on [−7,3] is

(f(3) − f(−7)) / (3 − (−7)) = (f(3) − f(−7)) / 10.

So read off the y-values at x = −7 and x = 3 from the graph, subtract f(−7) from f(3), and divide by 10. If you tell me the two y-values (or upload the graph), I’ll compute the numerical answer.
