Question

On a coordinate plane, a parabola with a solid boundary line opens down. It goes through (negative 5, 0), has a vertex at (5, 300), and goes through (15, 0). Which inequality in standard form represents the graphed region? y greater-than-or-equal-to minus 3 x squared + 30 x + 225 y greater-than-or-equal-to x squared + 10 x + 75 y greater-than-or-equal-to x squared minus 10 x minus 75 y greater-than-or-equal-to negative 3 x squared minus 30 x minus 225

PLEASE HELP!!!!!
