SOLUTION: I have to find the inverse of g(x) = the square root of x -4
In order to find the inverse you switch the x and y.
x = square root of y - 4
I have to get the y by itself,

Question 54929: I have to find the inverse of g(x) = the square root of x -4
In order to find the inverse you switch the x and y.
x = square root of y - 4
I have to get the y by itself, so I squared both sides, leaving me with:
x^2 = y - 4
x^2 + 4 = y
Is this the final answer? Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! Yes, you did it correctly, but you should finish the problem by replacing y with so you have:
To check you solution, remember that: and
Let's look at the first check: Simplifying this, you get: This checks out fine.
Now we'll do the second check: Simplifying this, you get: This also checks.
