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) = x2 + 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) = -x2 2x + 3
