Question

The function f(x)=0.04(8x-x^2) where x and f(x) are measured in miles. Find the rate of change of elevation at x=2.

Answer 1

so first you will have to substitute 2 in for x. now the equation looks like

f(2)=.04(8(2)-2^2) now u want to do what is in the parenthesis first now the equation looks like:

f(2)=.04(16-4) now do the subtraction and your equation now looks like

f(2)=.04(12) when you do the multiplication you get

f(2)=.48 and that's your answer please rate me brainliest
