Vertex form: reading a parabola's secrets — Homework

Read or convert each quadratic to vertex form.

  1. 1.State the vertex of y = (x - 7)² - 3.
  2. 2.State the vertex of y = -2(x + 4)² + 6.
  3. 3.Does y = 4(x - 1)² + 2 open up or down, and is it narrower or wider than y = x²?
  4. 4.Convert y = x² - 8x + 12 to vertex form, using vertex (4, -4).
  5. 5.A diver jumps: h = -16(t - 1)² + 20. What is the max height, and at what time?
  6. 6.Explain what the sign of a tells you about a parabola, using two examples with different signs.
