Each function in Exercises 9–12 is discontinuous at some value x = c. Describe the type of discontinuity and any one-sided continuity at x = c, and sketch a possible graph of f.
Explain why the Intermediate Value Theorem allows us to say that a function can change sign only at discontinuities and zeroes.
Write delta-epsilon proofs for each of the limit statements in Exercises .
