Determine whether each function's vertex is a maximum point or a minimum point and find the coordinates

Question:

Determine whether each function's vertex is a maximum point or a minimum point and find the coordinates of this point. Find the zeros, if any exist, and the y-intercept. Then sketch the graph of the function.

1. y = x - ¼ x2

2. y = - 2x2 + 18x

3. y = x2 + 4x + 4

4. y = x2 - 6x + 9
