x^2 + (y=11) 2 = 25
Step-by-step explanation:
Rewrite the equation in vertex form.
y = - 1/2 (x+0) ^2+3/2
Use the vertex form, y=a (x-h) ^2+k, to determine the values of a, h, and k
a = - 1/2
h = 0
k = 3/2
since the values of a is negative, the parabola opens down
find the vertex (h, k)
(0,3/2)
find p, the distance from the vertex to the focus
-1/2
find the focus
(0,1)
find the axis of symmetry by finding the line that passes through the vertex and the focus
x=0
find the directrix
y=2
use the properties of the parabola to analyze and graph the parabola
direction:opens down
vertex: (0,3/2)
focus: (0,1)
directrix: y=2
