Find the derivative of f(x) = x^3

Question

Show all the work please and thank you!

Answer 1

Where do you get stuck? The rule for powers is one of the first ones learned. Do you have to evaluate using the limit definition of the derivative?

If not, where does the difficulty arise is applying

d/dx(x^n) = n*x^(n-1)

??
For example,

(x^2)' = 2x
(x^6)' = 6x^5
. . .
