1. Problem Description
The problem presents the equation . We need to find the form of this equation. It looks like a parabola.
2. Solution Steps
The equation is given as .
We can rewrite this as .
The general form of a parabola opening upward or downward with vertex at the origin is , where is the distance from the vertex to the focus and from the vertex to the directrix.
In this case, we have , which gives . Since is negative, the parabola opens downward.
The vertex is at .
The focus is at , so the focus is at .
The directrix is , so the directrix is .
3. Final Answer
The equation represents a parabola opening downward with vertex at the origin. The equation can be written as .
