Find an equation of the parabola that satisfies the given conditions.
Focus F(8, 4), directrix y = −2.
***
Given data show parabola opens upwards.
Its basic form of equation:
, (h,k)=(x,y) coordinates of the vertex, p=distance from vertex to focus and directrix on the axis of symmetry
For given parabola:
axis of symmetry: x=8
x-coordinate of vertex=8
y-coordinate of vertex=(4+(-2))/2=2/2=1 (midpoint between focus and directrix on the axis of symmetry.
Vertex:(8,1)
p=3 (distance from vertex to focus and directrix on the axis of symmetry.
4p=12
