Answer:
Part A)
2nd and 5th choice.
Part B)

Step-by-step explanation:
For the given parabola, our focus is (-3, 2), and our directrix is given by y = 4.
Part A)
We are given a point (x, y) on the parabola.
Since our directrix is an equation of <em>y</em>, the distance from (x, y) to the directrix will simply be the absolute value of the difference in y-values. So:

Recall the distance formula:

Our distance from (x, y) to the focus (-3, 2) can be determined using the distance formula. Let (x, y) be (x₂, y₂) and let our focus (-3, 2) be (x₁, y₁). Therefore:

Hence, for Part A, our answers are the 2nd and 5th choices.
Part B)
Recall that by the definition of a parabola, any point (x, y) on it is equidistant to the directrix and focus. Hence:

Solve for <em>y</em>. Square both sides. We may remove the absolute value since anything squared is positive:

Square:

Rearrange:

Combine like terms:

Divide both sides by -4. Hence, our equation is:
