look at picture answer asap parabola directrix focus and vertex

Step-by-step explanation:

The given parabola has focus at:

and directrix at

This is a vertical parabola that opens downwards.

The equation is of the form;

p is the distance from the vertex to the directrix.

Since the vertex is at the origin, we have

We plug this value into the equation to get:

We solve for y to obtain:

The 3rd option is correct.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
