I use this with my Algebra I students to introduce quadratic functions. Students will identify features such as domain and range, axis of symmetry, vertex and x-intercepts. This foldable discusses both the ways to find these by hand and how to do it on the calculator.
This should be printed as 2-sided flipped on the short edge. Students will glue the first page to the second, then fold over to make a booklet. If assembled properly, there should be a binding that is about 1/2 inch wide.
