Question

How do I find the vertex form equation of this parabola using the graph and this information?

Answer 1

vertex is (3,1) the point where the parabola starts and opens down

Answer 2

y=a(x-p)^2+q

Answer 3

vertex (p,q)

Answer 4

y=a(x-3)^2+1............plug in when x=0 y=-16 to solve for a

Answer 5

a=-17/9

Answer 6

y=-17/9(x-3)^2+1
