Answer:
f^-1(x)=x/4-5/2
That is f to the negative one of x equals x over 4 minus 5 over 2.
Step-by-step explanation:
First replace f(x) with y
Replace every x with a y and replace every y with an x
Solve the equation from Step 2 for y
Replace y with f−1(x) f − 1 ( x )
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
