Anyway, you asked for some simple questions related to maximums and minimums.

1) If y = 4x - x^2 then find the maximum value of y and for what value of x does this value occur?

2) If y = x^2 - 6x + 10, determine if there is a local extrema and at what point it occurs.

3) If y = 10x + 1, determine if there is a local extrema and at what point it occurs.

Those are a couple of the most basic types of minimum/maximum problems. If you want tougher examples or want a question answered go to the "Help Me!" thread.
