GraphFree is a new online graphing tool for students and teachers. On GraphFree students can enter plot graph points manually or enter an equation or function to see a graph generated. Each graph can then be saved as an image to use in a document, a presentation, or in a SMART Notebook folder. GraphFree provides a helpful gallery of tutorial videos and an extensive guide for new users.
