    there is no critical point, but we have a point the the function is not defined, where x = 3

    yes because we get 1 = 0 whitch is false, that is not good, but them we have to see the function, what number will make a division by 0? ohh it's when x = 3 hum..., and the form of the function is hyperbolic... so you get in this conclusion
