Aparabola has its vertex at (2, 2), and the equation of its directrix is y = 2.5. the equation that represents the parabola is .

Check the picture below, based that the directrix is a horizontal line, and the vertex is below it, we know is a vertical parabola, and is opening downwards.

notice the distance "p" from the vertex to the directrix, is just 1/2

Re-do the question and enter the picture

X= -5because this is a single step equation so you would just have to divide -16 both sides for x to equal your solution
