You can put this solution on YOUR website!
Your given function might be better understood as f%28x%29=sqrt%28x%2B9%29-8.

graph%28400%2C400%2C-10%2C7%2C-10%2C7%2Csqrt%28x%2B9%29-8%29
Domain of this given function is from negative 9 to infinity.
Range of this given function is negative 8 to infinity.

The inverse of f will have the domain and range SWITCHED.


You can begin to find the inverse of f this way:
sqrt%28f%5E%28-1%29%28x%29%2B9%29-8=x
