Rational Inequalities

Graph of example

Graph of a rational polynomial with the equation $y=\frac{x^2+2x-3}{x^2-4}$. For $x$ values that are zeros for the numerator polynomial, the rational function overall is equal to zero. For $x$ values that are zeros for the denominator polynomial, the rational function is undefined, with a vertical asymptote forming instead.
