Let f(x)= x^4-4x^3+10

Where are the relative extrema, if they exist? Show all partsof the analysis necessary.

  • math -

    f ' (x) = 4x^3 - 12x^2
    = 0 for max/min
    4x^2(x-3) = 0

    x = 0 or x = 3

    take it from there

  • math -

    Yes , I did that part, what else do I have to do?
