What is the equation of the parabola, in vertex form, with vertex at (-2,-4) and directrix x = -6?
O A. (x+2) = 8(y+4)
B. (y+4)2 = - 8(x+6)
O c. (y+4)2 = 16(x+2)
O D.(x+4)² = 8(y+2)

Step-by-step explanation:

The distance between the vertex and the directrix is 4 units, that means that p = 4 in the equation

and h and k are the coordinates of the vertex. Filling in:

which simplifies to

step-by-step explanation:

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
