Strategy For Graphing Polynomials And Rational Functions

Asymptotes For Rational Functions. 1.Vertical Asymptote:Whatever makes the denominator zero is your vertical asymptote, as long as you do not have 0/0. Remember 0/0 could have a limit and it simply means a hole in the graph.2.Horizontal And Slant Asymptote:Is the limit of the rational f

    1. Strategy For Graphing Polynomials And Rational Functions 1. State the domain. 2. Find the Y-Intercept (x=0) and the X- Intercept (y=0) the easy ones in particular. You can use the synthetic division to find the easy zeros for the given polynomial function. 3. For rational functions ONLY, find the asymptotes. 4. Find Y’ and find the critical points. 5. Perform the sign analysis. 6. Graph the function.
