Homework Help: Analysis: Continuous Functions 2

    For (4), since this is an analysis class, I figured we can't use calculus to show this. I think I validly used the corollary that says if D is compact and f is continuous then there is a min and max of f on D.

    For (6), the key is to show if f is continuous and D is compact, then f(D) is compact.
