Featured Activities

Exploring Vertical Asymptotes

This lesson involves observing how changing the values in a rational function affects the continuity of the graph of the function. Students will explain how the values in a rational function determine the vertical asymptotes.

Crossing the Asymptote

This lesson involves the graph of a rational function of the form r(x) = p(x) / q(x). Students will manipulate graphs of rational functions and their asymptotes to determine whether they intersect.

Polar Coordinates

This lesson involves a brief introduction to the polar coordinate system. Students will determine the location (quadrant) of various points given in polar form and recognize cases in which a point lies on an axis. Students will convert points between polar and rectangular form.
