[Athen] Graphing functions

[Schwarte, David M.]

Hello Rachel,

I am not sure how often this occurs, but I remember running into some occasions where an actual graph was really the only option.  In my case this was not for math but Controlls in Mechanical ingineering.  Frequently there were multiple graphs of the same information.  Sometimes the graphs needed to be compared or contrasted to find the necessary answer.  Sometimes part of determining the answer would require knowing which type of graph to use.  Back when I was a student I used enlargement software and/or a CCTV.  Now I would probably consider something like a Tiger or Phoenix tactile graphics embosser.  Some of the choice of how to deal with the graphs would also depend on the importance of the graphs to the student's class and course of study.

Hi all,

It's been a while since I've worked on Math accessibility, and could use a little help. I have some Math instructors who are trying to create handouts and we've run into a snag with graphs of functions. Normally my recommendation would be to describe the graph/function using points, what the lines are doing visually, etc. However, the answer that I received from instructors was if we describe the graph that way, it would give the answer away.

Are there other recommendations for describing the graph, or graphing tools?
