Answer:
D) (-5, 1)
Step-by-step explanation:
To make a table of the inverse function, swap the column headings X and Y. To find the answer to this question, find the point in the revised table.
The desired point is (x, y) = (-5, 1), corresponding to the original table point (1, -5).
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.
