Question

find the average rate of change for the following functions on the indicated intervals. f(x)=x^3-2x; (0,4)

Answer 1

14

Answer 2

how did you get that?

Answer 3

find the derivate of the given function and substitute the value from the piont

Answer 4

sorry for my english ,the average rate of change is the change in y divided by the change in x ,4^3-8=56, 56/4 =14

Answer 5

i am confused but i think -2 is the answer

Answer 6

how did you get -2?

Answer 7

the derivative the given function is 3x^2-2,if u substitute the value of x i e 0 then it gives -2

Answer 8

Nope,caution!it is average change ratio and the X is in the interval (0,4)
