Let f(x) = 4 ⋅ sin x + 8 Find f^-1 ( x )

Question

Let f(x) = 4 ⋅ sin x + 8

Find F^-1(x) =

I am struggling with this question. My computer software is not accepting my answer. Can anyone provide me an exact answer to this solution.

Answer 1

f^-1(x) = arcsin[(x-8)/4]

can also be written

f^-1(x) = sin^-1[(x-8)/4]

it is possible your software is too restrictive in what grouping format it is willing to accept.

good luck.
