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

Since the parabola opens right, then the a-value had to be...

• positive

• negative
