Answer:
So, the inverse of function
is

Explanation:
We need to find the inverse of the given function

To find the inverse we replace f(x) with y
Now, replacing x with y and y with x
Now, we will find the value of y in the above equation
Multiplying both sides by -2
Taking square on both sides

Finding value of y

Replacing y with f⁻¹(x)

So, the inverse of function
is
