Step-by-Step Guide to Graphing Rational Functions
We're graphing rational functions!
To do this, we are going to follow 4 steps:
1. Factor
2. Find the Asymptotes:
Vertical (Check for Holes)
-Horizontal or Slant
3. Find the x-intercept(s) & y-intercept
4. Figure out the general shape of your graph by applying what you know about the function, or by plugging in points to get ordered pairs.
It's also a good idea to check your work after graphing with a graphing calculator.
