2. Rational Functions and Asymptotes
A rational function is a function written in the form of a polynomial divided by a polynomial.
Domain: is the x-values
Remember you cannot have a zero in the denominator of a fraction

3. Rational Functions and Asymptotes
Vertical Asymptotes: To find the vertical asymptotes set the denominator equal to zero and solve for x.
Horizontal Asymptotes: To find the horizontal asymptotes compare the degree of the numerator to the degree of the denominator.

4. Rational Functions and Asymptotes
Horizontal Asymptotes:
If the degree of the numerator is bigger than the degree of the denominator, then there is not a horizontal asymptote.
If the degree of the numerator and the degree of the denominator are the same, then the horizontal asymptote is y = leading coefficient over leading coefficient.

5. Rational Functions and Asymptotes
Horizontal Asymptotes
If the degree of the denominator is bigger than the degree of the numerator, then the horizontal asymptote is y = 0
Asymptotes are equations:
Vertical Asymptotes are x = #
Horizontal Asymptotes are y = #
