a parabola has a focus of (-2,3) and a directrix of y=1. what is the axis of symmetry, the vertex, and which direction does the parabola open?

Answer 1

Plotting the focus and the directrix, the vertex will be half way between them. The vertex is (-2,2) The axis of symmetry is the x coordinate of the vertex, x=-2. Finally, the parabola opens up.
