y = x^2 / x-5
graph the function
-identify the domain and any symmetries
-find the derivatives y' and y"
-find the critical points and identify the function's behavior at each one
-find where the curve is increasing and where it is decreasing,
-find the points of inflection
-determine the concavity of the curve
-identify any asymptotes
-find the coordinates of absolute extreme points, if any
