Question

Which expression could you use to find the average rate of change for this function over the given interval.

f(x) = 2x2 − x + 6; [−2, 3]

A)
f(2) − f(3)
3 − (−2)

B)
f(−2) − f(3)
2 −3

C)
f(3) − f(−2)
3 − (−2)

D) −
f(3) − f(−2)
3 − (−2)

Answer 1

Its C. I just got it wrong

Answer 2

Answer:

c

Step-by-step explanation:

f(3) − f(−2)

3 − (−2)

f(b) − f(a)

b − a
