The function f is continuous on the interval [3, 13] with selected values of x and f(x) given in the table below. Find the average rate of change of f(x) over the interval [3, 13]

Question

The function f is continuous on the interval [3, 13] with selected values of x and f(x) given in the table below. Find the average rate of change of f(x) over the interval [3, 13]

f(x)	2	8	10	12	22

x 3 4 7 10 13

Answer 1

r_av = (f(13) - f(3))/(13 - 3) = (22 - 2)/10 = 2
