Given the function f(x) = 5x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.

nadezda [96]

Average rate of change from x = 0 to x = 1 is $\frac{f(1)-f(0)}{1-0}= \frac{5(1)-5(0)}{1}=5$
Average rate of change from x = 2 to x = 3 is $\frac{f(3)-f(2)}{3-2}= \frac{5(3)-5(2)}{1}=15-10=5$
The average rate of change of both sections are equal.
