Exploring Equations of the Form
by Mark Cowart (EMT668/Summer 1998)
Equations of the form yield some interesting graphs
and enable students to form generalizations about the graph of the equation
when n is positive or negative, or large or small, or possibly negative
or a fraction. Furthermore, students can gain experience using Algebra Xpressor,
Graphing Calculator 2.0, or any of the TI 80 series calculators while exploring
quickly and efficiently several graphs of these particular equations.
Graph the following equations. Sketch each graph and look
for any patterns. Discuss your findings and make some generalizations about
the graphs of

Click here for the graphs of several of these equations (for you to compare).
Why do you think even powers of the n exponent approach the graph of a square as n increases? What about odd powers?
Create some more equations of the general form of your own. Describe what happens if the exponent, n, is negative or a fraction. Explore several possibilities and make some generalizations.
