Expert Solution
Step 1

Given function is fx=-2x+4+5.

To find the graphical representation of f-1x.

Solution:

Steps for finding inverse of a function.

`1. Replace fx with y.

2. Then replace y with x and x with y.

3. Then solve for y.

4. And then replace y with f-1x.

Step 2

Finding the inverse of the given function using the above steps.

y=-2x+4+5

Now, replace y with x and x with y.

x=-2y+4+5

Now, solving for y.

x=-2y+4+5x-5=-2y+4x-5=-2y-8-2y=x-5+8-2y=x+3y=x+3-2y=-x-32
