I am lost on these questions.

Can somebody PLEASE help?

1. X2=-4y Find the vertex, focus and directrix of the parabola and sketch the graph.

2. Find the equation in standard form of the parabola with focus (-2, 4) and directrix x = 4

3. Find the center, vertices, foci and sketch the graph of the ellipse with the following equation. 25x2+12y2=300

Thanks for helping me keep my sanity!!
