Using graphing software, students explore the transformations of quadratic functions: Students will manipulate the parent graph f(x)= x2 into translations, dilations, and reflections: Use the example in the book or chose their own example. On a separate sheet of paper and a poster, write and graph the parent form of the quadratic and write an equation of an assigned transformations of the parent graph and explain what happens to each graph based on the equation.

Transformations that occurred from manipulating slider a.
