Write delta-epsilon proofs for each of the limit statements in Exercises .
.
For each limit statement , use algebra to find δ > 0 in terms of > 0 so that if 0 < |x − c| < δ, then | f(x) − L| < .
For each functionf graphed in Exercises23–26, describe the intervals on whichf is continuous. For each discontinuity off, describe the type of discontinuity and any one-sided continuity. Justify your answers about discontinuities with limit statements.

Use what you know about one-sided limits to prove that a function is continuous at a point if and only if it is both left and right continuous at .
