Find the derivative of f(x) = 5x^3 -2x^2 + 9
------------
Hint:
If f%28x%29+=+a%2Ax%5En
f'(x) = n%2Aa%2Ax%5E%28n-1%29

Derivatives will get a lot more complicated than this one.
Then there's integrals.

Use the power rule, and the fact that the derivative of the sum of two or more functions is equal to the sum of the derivatives of those functions.



Note that constant functions have zero slope relative to x.
