Chapter 3.2, Problem 4E

In Exercises 1-6, find all values $x=a$ where the function is discontinuous. For each point of discontinuity, give $\text{(a)}f\left(a\right)$ if it exists, $\text{(b)}\underset{x\to a^{-}}{\lim }f\left(x\right),\text{(c)}\underset{x\to a^{+}}{\lim }f\left(x\right),\text{(d)}\underset{x\to a}{\lim }f\left(x\right)$, and $\text{(e)}$ identify which conditions for continuity are not met. Be sure to note when the limit doesn’t exist.
