Title: New Exercise: Graphing Rational Functions

Hello,

I designed a new exercise for graphing rational functions. The exercise requires students to find key points and asymptotes of graphs of the following functions:

f(x) = P(x) / Q(x), where P and Q are factorable quadratics.

In each case, P and Q share a factor, so the graph has one x-intercept, one vertical asymptote, and one hole. Students must drag the points and asymptotes to the correct places on the graph to solve the problem.

I hope you like it!
