A is your answer
Step-by-step explanation: B is wrong because if it was -6 then it would equal -216
has two points of discontinuity at
, where
.
We have

so as long as
, we can cancel
and be left with
. Then as
, we have

The limit exists, so the discontinuity at -1 is removable (so definitely not C or D).
Meanwhile,

does not exist, so the discontinuity at 1 is non-removable, making A the correct answer.
