Ok. Me and my class is going to do a 30-minute algebra test and my teacher gave us some practice sheets. One of them has this problem: Given f(x) = x^2-6x+4. Find the minimum and maximum of f(x), given that 1 <= x <= 4. HELP ME!

I get a sneaking suspicion that a minority of the posts here are from people just wanting someone to do their homework for them so they can copy it, hand it in and take the credit for it. Does anyone else here share the same suspicion or am I out in left field?
