# 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. $y=-0.1x^2+2.7$
