Using a directrix of y = 2 and a focus of (3, −4), what quadratic function is created? (5 points) f(x) = one twelfth (x − 3)2 − 1 f(x) = − one twelfth (x − 3)2 − 1 f(x) = − one sixth (x + 3)2 + 1 f(x) = one sixth (x − 3)2 + 1

Check the picture below, so keeping in mind that, the distance "p" from the vertex to either the focus point or directrix is the same, that means the vertex is half-way in between those two folks.

now, the directrix is above, and the focus point is below, that means is a vertical parabola, meaning the "x" is the squared variable, and it opens downwards, meaning the distance "p" is a negative value, in this case is -3.
