1. Quadratic Graphs

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

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

4. What does this quadratic graph look like?
y = x2 + 1 ?

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

6. What does this quadratic graph look like?
y = x2 + 2x + 1 ? x -3 -2 -1 1 2 3 y

7. What does this quadratic graph look like?
y = x2 + 5x + 6 ? x -3 -2 -1 1 2 3 y

8. Which of these are ‘n’ shaped and which are ‘u’ shaped?
y = x2 + 3x + 6
y = x2 + 3x - 6
y = x2 - 3x - 6
y = - x2 + 3x - 6
y = - x2 +3x + 6
y = - x2 - 3x + 6
y = x2 - 3x + 6
y = - x2 - 3x - 6
