In other words, R(x) is a rational function if R(x) = p(x) / q(x) where p(x) and q(x) are both polynomials. Recall that a polynomial is any function of the form ...

I need some help understanding the concept of "holes" in a graph.

It's usually equal to 1, but when x = -3 it's not equal to 1, it's undefined, it doesn't exist, it's meaningless. Therefore, you are only ...

If you make sure that the denominator, and only the denominator is zero at x=-2, you can be sure that the function will have an x=-2 asymptote. If the numerator ...

Implicit equation between rational function and its derivative

The magic word is "implicitization". Consider the curve in P2 given by C=(f(t),f′(t)). (as pointed out by Robert Bryant in the comments).
