This foldable is designed as a step by step guide for students for graphing rational functions. From top to bottom, the individual doors assist students with (1) simplifying rational expressions, (2) finding points of discontinuity, (3) identifying vertical asymptotes, (4) identifying horizontal asymptotes, (5) identifying slant asymptotes, (6) finding x-intercepts, (7) finding y-intercepts, and (8) stating the domain and range. There are two foldables per printed page. Print double sided (flip along short edge) and cut to separate the two foldables. Then, cut along the solid lines to create each door. Great for Algebra 2 or Pre-Calculus notebooks!
