This is ONLY THE DIGITAL FILE for the posters. They are designed to be printed 18 inches by 24 inches.
The 12 parent functions included are: linear, quadratic, cubic, square root, absolute value, rational, sine, cosine, exponential, natural log, greatest integer, and logistic.
The colors for each poster vary. The poster has the name of the function, the graph, and the equation.
You will have to have these printed on your own - there are several places to get posters printed relatively cheaply.
I prefer to use http://www.shortrunposters.com/ to print mine - you can order several at one time & save on shipping!
