a. Find the coordinates of the vertex.

b. Find the y-intercept

Y= -1/4(x+4)^2 -5

Y= -3(x-4)^2 +8

Y= 0.5(x-6)^2 -1

Y= 2(x-1/2)^2 +4

Thank you! :)

1, coordinates at (-4,-5), Y int. @ -9

2, coordinates at (4,8), Y int, it does not cross the y axis so there is no y int.

3, coordinates at ( 6,1), Y int. @ 17

4, coordinates at (.5,3.6) Y int. @ 4.5
