1.To find the inverse, first change to x,y notation.

Then interchange the positions of x and y and solve for y.



The solution for the new y is the inverse function.

2. Graph both functions.

The domain of f(x) is restricted because of the square root function.


and the range is bounded by zero.
Domain f(x):(,)
Range f(x):(,)
