Answer
See figure: vertex $(0,0)$, focus $(2,0)$, and directrix $x=-2$
Work Step by Step
Step 1. From the given equation, we can find $p=\frac{8}{4}=2$ with the parabola opening to the right as shown in the figure.
Step 2. We can identify the vertex at $(0,0)$, focus at $(2,0)$, and directrix as $x=-2$
