Just plug in -3 for x. So it will be -(-3)^+ 1
Which is 3^+1.
I'm confused by your ^ sign I'm not sure if this is supposed to be squared or not...? But just solve/simplify the equation.
Hope this helps!

Lostsunrise [7]

Answer:

The inverse of f(x) is  f ^ {- 1}(x) = x + 2

Step-by-step explanation:

To find the inverse of the function f (x) = x-2, perform the following steps:

1) do y = f (x)

y = x-2

2) Solve the equation for the variable x.

y + 2 = x -2 +2

y + 2 = x

3) exchange the variable x with the variable y

y + 2 = x ----> x + 2 = y

4) Change the variable y by f ^{- 1}(x)

Finally the inverse function is:

 f ^ {- 1} (x) = x + 2
