Answer:
-13/400
Step-by-step explanation:
The pertinent formula is
change in f(x) over [a, b] f(8) - f(0)
a. r. of change = --------------------------------------- = ----------------
change in x over [a, b] 8 - 0
Continuing these calculations, we get:
2(8) - 2 2(0) - 2 14/8 -2/8
(1/8) -------------- - (1/8) ------------- = ----------- - -----------
5(8) - 6 5(0) - 6 40 - 6 -6
7/4 1/4
This simplifies to average rate of change = ------- - --------
34 6
7 1
= ------------- - ---------- = -13/400
136 24
