  1. Identifying Quadratic Graphs

  2. positive quadratic y = x2negative quadratic y = –x2

  3. What does this quadratic graph look like? y = x2

  4. What does this quadratic graph look like? y = - x2 ?

  5. What does this quadratic graph look like? y = x2 + 1 ? What does adding one do to the graph?

  6. What does this quadratic graph look like? y = x2 + 2x + 1 ? Fill in the chart on your own please

  7. What does this quadratic graph look like? y = x2 – 3 ? What does subtracting 3, do to the parabola?

  8. What does this quadratic graph look like? y = x2 + 5x + 6 ? Please fill in the chart on your own.

  9. Which of these are a happy face shape and which are a sad face shaped? y = x2 + 3x + 6 y = x2 + 3x - 6 y = x2 y = - x2 + 3x - 6 y = - x2 +3x + 6 - 3x - 6 y = - x2 - 3x + 6 y = x2 - 3x + 6 y = - x2 - 3x - 6
