MPM2D1-02 Finding an equation in vertex form 2016-11-07

We reviewed the work from Friday (graphing using a step pattern) and then started into finding equations of quadratics in vertex form. I gave an example in class, then I assigned some homework.

Here are a couple more examples to help solidify the concepts:


and here is a blank version, including some practice that we’ll be doing tomorrow:


EDIT: Forgot to post the homework!

For each equation below, find a h k , and the vertex. Each equation is in the form y=a(x-h)^2+k .

  1. y=x^2+17
  2. y=(x+7)^2
  3. y=(x-1)^2+18
  4. y=2x^2-8
  5. y=-\frac{1}{2}(x-7)^2+\frac{4}{3}
  6. y=-0.1x^2+2.7
