Students will explore rational functions graphically and algebraically to identify singularities and asymptotes, both vertical and horizontal.

Key Steps

  • Image

    Students engage in an exploration of asymptotes involving graphing, exploration of a table of values, and algebraic manipulation.

  • Image

    Factoring is applied as a means to identify singularities and determine vertical asymptote locations.

    Students will use the Transformation Graphing application to see the effects of different values on the graph of the function.

  • Image

    Students apply their findings regarding asymptotes and learn to place dashed lines representing asymptotes on function graphs.
