McBroom, Douglas C. – 2001
This guide provides students with practice for all the major types of graphs they are likely to encounter. It includes information on graphs of various families of algebraic functions; bar, line, and circle graphs; the creation, reading, and interpretation of graphs; and the use of graphing calculators.

Pelech, James; Parker, Jacquelyn – Mathematics Teacher, 1996
Uses a graphing calculator to demonstrate that dividing by a fraction is the same as multiplying by the reciprocal. Students graph a division problem and an equivalent problem, multiplying by the reciprocal. They find that the graphs are the same. (SKS)

Perera, Vic – 2002
This paper presents some ideas on how to utilize TI-83 Plus calculators to perform division of one polynomial (the divided) by another polynomial (the divisor) and how that procedure might be incorporated into a college algebra lesson. Four ways to obtain the quotient and remainder when dividing a polynomial by a first-degree polynomial are…
