Question 645721: What is the inverse of +f%28x%29+=+4%2Asqrt%284x%2B1%29+ ? I have tried about 10 different routes of solving but cannot get the exact right answer. I have narrowed it down to +4x+=+%28y%2F4%29%5E2-1+ . Working backward, I don't even understand how an inverse function could be solved to get an original function like that.

From where you are, divide both sides by 4. Simplify the ugly compound fraction. Swap the positions of the and variables. And finally, replace with .
