Defined in the interval 1<(or equal to) x <(or equal to) 9
I've found the derivative:
But don't know what to do next....

What exactly is the question?
Oh sorry. The maximum and minimum value (both the x position and the actual value, though obviously finding one it will be easy to find the other). That's why i took the derivative but I don't know how I would set that to zero or what...
Establish same common denominators:
whenever the denominator is zero you will have an asymptote unless it factors out and then you have a whole in the graph.
Your critical values to test are when the numerator and denominator are 0.
check the critical values for extrema ... don't forget the endpoints.
Thank you both of you!
