Chapter 6.3, Problem 16E

13. a) Determine the average rate of change over the interval x = [1, 5] of the function y = 3x + 1. b) Regardless of the interval, what will the average rate or instantaneous rate of change be for the function y = 3x + 1? Explain. Expand your answer to include linear functions in general.

The graph shows the function f(x). What is the average rate of change for the function f(x) over the interval [0,3]? Enter your answer as a number, like this: 42

Please write the answer clearly and readable. Thank you.
