Question

Calculate the average rate of change of f(x) = 3x2 + 2x + 1 for 2 ≤ x ≤ 4. A) 10 B) 20 C) 37 D) 40

Answer 1

(im typing a few words for me to anwser) its B

Answer 2

we have been asked to find the average rate of change of f(x) = 3x^2 + 2x + 1 for 2 ≤ x ≤ 4.

Average rate of change of a function
`=(f(b)-f(a))/(b-a)` over the interval [a,b].

`image`

The average rate of change of f(x) = 3x^2 + 2x + 1 for 2 ≤ x ≤ 4 is 20
