Reading and Interpreting Graphs of Functions

The concepts at play are simple.  A function has exactly one output for each input.  A graph is a picture of all inputs and outputs, with y representing the output and x representing the inputs.

Yet, to read a graph and glean information from it about the function requires a little thought and consideration, at least initially.

That’s what this page is all about, helping you learn how to read and interpret graphs.

Start by reading the notes, then watch the video.  Try the practice problems to test your understanding.
