Subject: Re: Graph sketching

I am sure the most common curve sketching tool used in middle schools and
high schools is the graphing calculator. High schools may also use Best
Grapher (Venture Publishing), Maple, Derive, and packages that come with some
of the textbooks. These graphers do not, however, guide students through an
analysis of a function.
