I just need someone to see if my amswers are correct 1) Differentiate the function: f(x) = (-3x-1)^4 is 4(-3x-1)^3

OpenStudy (anonymous):

2 more

OpenStudy (anonymous):

answer is -12(-3x-1)^3

OpenStudy (anonymous):

nope you forgot to take the derivative of the inner function

OpenStudy (anonymous):

Differentiate the function (x^2 - 4x)^3 is 3(x^2-4x)^3 (2x-4)

OpenStudy (anonymous):

frat is correct

OpenStudy (anonymous):

wait so wat is it?? @outkast

OpenStudy (anonymous):

it's -12(-3x-1)^3

OpenStudy (anonymous):

so number 2 is correct?

OpenStudy (anonymous):

so your outer function is (u)^4 and your inner is (-3x-1) so when doing chain rule (outer*inner) you get 4(u)(-3) = -12(u)=-12(-3x-1)
