Question

Find f inverse if f(x) = x^3 + 2
PLease HELP!!

Answer 1

This can be seen as:
\[y = x^3 + 2\]
To find the inverse you must swap x for y and solve for y.
\[x = y^3 + 2\]

Answer 2

@waterineyes was yours not correct?

Answer 3

It was correct..

Answer 4

His was 100% correct. It's important to see why.

Answer 5

why did you delete it?

Answer 6

I again provide you the solution:

Now I am starting where @qpHalcy0n left:

\[x = y^3 + 2\]

\[y^3 = x-2\]

\[\large \color{green}{y = \sqrt[3]{x - 2}}\]

Answer 7

Now replace y by \(f^{-1}(x)\).

Answer 8

so final answer is f^-1x=cubed root x-2? @waterineyes

Answer 9

Yes it is the answer..
