Kaylah Booker · Answer 1

d. x^2=-8y

Step-by-step explanation:

Based on the given conditions, the vertex of the parabola is located in origin. With the opening being to the left, it can be said that the squared term is y and the distance from the vertex to the focus (focal length) is 12. By the standard equation of a parabola opening to the left, below is the equation.
