Answer 1

I can’t see the graph you mean, so I can’t pick one of the choices for you. The average rate of change on [1,3] is

(f(3) − f(1)) / (3 − 1) = (f(3) − f(1)) / 2.

Read the y‑value at x = 3 and the y‑value at x = 1 from your graph, subtract f(1) from f(3), and divide by 2. If you want, upload or describe the graph (the y‑values at x=1 and x=3) and I’ll compute which choice is correct.
