$3\mathrm{.}2$

EXERCISES

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

I need help with $1,2,$ and $6$ please
