    Differentiation problem and finding maximum, need helping :)?

    have a few problems with these questions, can you help :)

    Using differentiation, find the MAXIMUM value of the following functions?

    1. f(x) = x2 / 4 + 4 / x
    2. f(x) = xe-2x2
    3. f(x) = sqrt(x - n) / x ; n>0

    hope you guys can help !

    We can help, but only after you show us how you would approach them. How do you find the min and max of functions?
