I've used this book of parent graphs in both my sophomore and junior level math classes. It has pages for the following functions: Linear, Quadratic, Absolute Value, Square Root, Cubic, Cube Root, Exponential, and Rational.
The first two pages have spots for all of the definitions of the key features, then there is a chart for each function to fill out its key features. There is also a place to graph each function and to write in key points for the function, to use when graphing.
I have included a key, instructions, and a few teaching ideas. This is something that I make my students keep with them and refer back to throughout the unit. I have found it is a great way to teach them to use their notes and to think through how to use their resources, before automatically asking for help.
