1)

Define f: R -> R by f(x) = x^2 - 3x + 5. Use the definition of continuity to prove that f is continuous at 2

2)

Let f: D->R and let c be an element of D. We say that f is continuous at c if for every e>0 there exists a q>0 such that |f(x) - f(c)| < e whenever |x-c| < q and x is an elemend of D.

If f si continuous at each point of a subset S of D, then f is said to be continuous on S. If f is continuous on its domain D, then f is said to be continuous - April 10th 2007, 06:10 PMThePerfectHacker
I have absolutely no idea what your question means.
