Complete parts a – c for each quadratic function.

a. Find the y-intercept, the equation of the axis of symmetry and the x-coordinate of the vertex.

b. Make a table of values that includes the vertex.

c. Use this information to graph the function.

1. f(x) = 2x2

2. f(x) = x2 + 4

3. f(x) = 2x2 – 4

4. f(x) = x2 – 4x + 4

5. f(x) = x2 – 4x – 5

6. f(x) = 3x2 + 6x – 1

7. f(x) = -3x2 – 4x

8. f(x) = 0.5x2 – 1

9. f(x) = ½x2 + 3x + 9/2

Determine whether each function has a maximum or a minimum value. Then find the maximum or minimum value of each function.

10. f(x) = 3x2

11. f(x) = x2 – 8x + 2

12. f(x) = 4x – x2 + 1

13. f(x) = 2x + 2x2 + 5

14. f(x) = -7 – 3x2 + 12x

15. f(x) = -½x2 – 2x + 3
