Thread: Graphs for breaking horizontal asymptote misconception

    Graphs for breaking horizontal asymptote misconception

    I'm wanting to introduce limits as x approaches infinity by having students classify graphs as having, or not, vertical and horizontal asymptotes. Does anyone have a bunch of graphs that would help fight the misconception that it is 'always approaching?'

    Have you looked at Beth Cory's and Ken Smith's article on "Delving into Limits of Sequences" in the August issue of The Mathematics Teacher? This is specifically one of the very misconceptions that they take on in that article and the accompanying activities. Here's the link: http://www.nctm.org/eresources/toc.asp?journal_id=2
