This Reflections of a Quadratic Function lesson plan also includes:
High schoolers are asked to explain the relationship between f(s) and f (-x). They are asked to determine how the equation of f(x) differs from the equation of f(-x). Students determine the conditions when f(x) is the same as f(-x). They graph f(-x). High schoolers define an even function f(x) as any function that holds the property f(-x)=f(x).
