How do you find the inverse of #f(x) = 4 / (x+2)#?
Replace the original x with y and original y with x and solve for y.
We can find the inverse of any function by replacing the original function's x with y and y with x and solving.
For this function,
Now we flip the x and the y to get:
Now we solve for the new y:
So our inverse function is:
