Now, let's go through the exercise again, only this time we want to use computations as the arguments. Start with the vertex form for a quadratic equation: y = a(x - h)^2 + k. It's okay to assume values for a, h and k so that you're working with a specific example of one, but it's also okay to use the order of operations implied by the general equation form. What you want to explore is what happens when you use x = h, versus what happens when you use other values for x. The answers are not as important as the calculations and how they simplify. Let me know what you find.
