Question

find the derivative of f(x) = x^4+ x^3- 2x^2-x

Answer 1

4x^3+3x^2-4x-1

Answer 2

these are the most basic derivatives... you NEED to be able to do these yourself. do you understand how to do them?

Answer 3

Yep, I agree Edge.

Answer 4

ticorn, if your book isn't helping you then try looking at Paul's online math notes.

Also, the format for these derivatives is:

f(x) = x^n
f'(x) = nx^n-1
