I need help to find the graph given the function f(x)=(x^2-9)/(x+3) if anyone could show me how to get the domain and range also if there is any Oblique.
---------------
Domain is "All Real Numbers except x = -3 because if x = -3 y would be 0/0
which is undefined.
---------------
Range is "All Real Numbers except y = -6" because x cannot be -3, so
x-3 cannot be -6.
--------------------
Oblique = (x^2-9)/(x-3) = x+3 which is a line.
