Question

Find the average rate of change of the function f(x)=2 ⋅ x^4 on the interval on the interval 2 ≤ x ≤ 4

Answer 1

Btw this has to do with something about power functions so the function isn't 2x^4 it is 2*x^4

Answer 2

same thing?

Answer 3

No

Answer 4

I know the answer to this but I just don't know how to get to it.

Answer 5

You want to find the first derivative of the function first.

Answer 6

Is that like the inverse of this function?

Answer 7

The anwer is 992/5 but I just need to know the work to get to the answer.

Answer 8

That is the derivative formula
f(x) -f(a)/(x-a)

Answer 9

(f(x) - f(a))/(x-a)

Answer 10

. It is just calculating the slope (average rate of change over that interval). Just take y2 - y1 over x2-x1

Answer 11

If I did the y2-y1 thingy, the anwer would be 240 but that isn't correct....
