Answer:

Step-by-step explanation:
The equation of a horizontal parabola in the standard form:

(h, k) - vertex
if a > 0, then open right
if a < 0, then open left
We have the vertrex (-1, -3) and the parabola is open left (a < 0).
Therefore the equation of a given parabola could be:

X-int: none
Y-int: (0,27)
Vertex: (-3,18)
AOS: x= -3
Max & Min Value: (-3,18)
The correct answer is 330.
Use the metric relations,
AC*CD=BC^2
=>
5*CD=9^2
solve for CD
CD=9*9/5=16.2
