MPM2D1-01 Graphing Parabolas, Reading Vertex Form 2016-11-07


We spent today practising the skills from Friday (graphing using a step pattern). A number of people had trouble with reading the vertex accurately from the equation. Your homework tonight (if you didn’t finish in class) is this:

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
