I'm having a lot of trouble on my calculus homework right now. Here are the problems:

USE FUNCTION: f(x) = 3x^4 - 4x^3 + 6
1) Find all critical points of y = f(x). Identify each one by its x coordinate.
2) Use the first derivative test to determine each critical point of f(x) whether it is a local minimum, local maximum, or neither.

thanks
