###### Question details

Outcome: *“Can I explain how Coordinate Geometry connects properties of geometric objects (points, circles, lines and parabolas) with properties of algebraic objects (equations, their forms and their solutions).”*

1. Which of the following *equations* will have a graph that is a *parabola *with its directrix parallel to the x-axis?

a) 4y = x^{2} + 6x + 5

b) y = 6(x + 2)^{2} – 14

c) y^{2} = 3x^{2} – 2x + 1

d) y = 3(x – 1)^{3} + 5

e) y = 1/ 2x^{2} + x – 5
