4. Rational Function Cards: Investigation 1
Use your graphing calculator to complete a sketch of each graph. Show each in FACTORED form. Based on what you have done,
What causes a vertical asymptote?
What causes a hole in the graph?

5. Rational Function Cards: Investigation 2
Use your graphing calculator to graph each rational function. Categorize based on if there is a horizontal asymptote or slant asymptote.
What causes a horizontal asymptote?
What causes a slant asymptote?
