Find the vertex, focus, and directrix of the parabola with the given equation. 

• vertex:  (3, 2) focus:  (5, 2) directrix:  x = 1

•  vertex:  (-3, -2) focus:  (-1, -2) directrix:  x = -5

• vertex:  (2, 3) focus:  (4, 3) directrix:  x = 0

• vertex:  (3, 2) focus:  (1, 2) directrix:  x = 5

How WIDE will this parabola be?

• 12

• 3

• (2,3)

• 24

In a parabola, "p" tells you the distance from the ​ (a)   to the ​ (b)   and ​ (c)  

• vertex

• focus

• directrix

• origin

• parabola

• axis
