Hey can you me posted picture of question

The inverse of the inverse function will give us back the original function.

So the inverse of the inverse function x² -2 will be √(x+2), which i s thus our original function.

So, the answer to this question is option A.

A way to validate the answer is take the composition of the original function and its inverse, the will give the result equal to x

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
