Question

use the definition of a derivative to find f'(x); f(x)=(x^3) - (x^2)

Answer 1

f'(x) = 3x^2 - 2x

Answer 2

wait how did you get there

Answer 3

sorry, haha. so there aren't any exact formulas here. its just the simple understand of a derivative. so we're going to work with one derivative at a time. first lets work with, x^3. the derivative rules say, bring the given exponent to the front of the term and make it a coefficient and decrease the given exponent by 1. Lemme draw this out..
