Characteristics of Graphs & Functions Foldable

I created this Characteristics of Graphs & Functions Foldable recently. After doing domain and range with my Algebra 2 class, my next goal was for students to be able to recognize x-intercepts, y-intercepts, maximum and minimum values, and vertical and horizontal asymptotes.

I summarized these for my students in a booklet foldable for their interactive notebooks.

My students seemed to easily grasp the concepts of intercepts, maximums, and minimums.  The concept of an asymptote seemed to elude most of them.  I did use the HOY VUX mnemonic to help my students remember how to write the equations of horizontal and vertical lines.  But, I’m still not happy with my introduction of asymptotes.  I taught this unit before teaching rational expressions, so I couldn’t exactly explain to my students what caused asymptotes.  This is definitely towards the top of my “figure out how to teach this better next year” list.
