Answer: y= -6x + 4
Step-by-step explanation:
To find the inverse of a function:
1. Replace f(x) with y.
2. Switch x and y.
3. Solve for y.
4. Replace y with f-1(x) (notation for inverse fucntions)

Let's use y instead of f(x).

Switch the variables...

Now, we solve for y.



Now, just put that inverse function notation on there.
