Is a constant.

The equation of a parabola in standard form is given by y^2 = 4ax, where a is a constant. This equation represents a parabola that opens either to the left or right, depending on the sign of a. If a is positive, the parabola opens to the right, and if a is negative, the parabola opens to the left.

The vertex of the parabola is at the origin (0,0) and the focus is at the point (a,0). The directrix is the line x = -a.

The equation y^2 = 4ax can also be written as y = ±√(4ax), which represents two branches of the parabola. The positive branch represents the upper half of the parabola, while the negative branch represents the lower half.

The equation y^2 = 4ax can be used to find the coordinates of other important points on the parabola, such as the vertex, focus, and directrix. These points can be determined by plugging in specific values for x.

For example, if we let x = 1, then y = ±√(4a). This gives us two points on the parabola, (1, ±√(4a)). These points are symmetric about the y-axis.

Similarly, if we let x = -1, then y = ±√(-4a). This gives us two points on the parabola, (-1, ±√(-4a)). These points are also symmetric about the y-axis.

In summary, the equation y^2 = 4ax represents a parabola that opens either to the left or right, depending on the sign of a. The vertex is at the origin, the focus is at (a,0), and the directrix is the line x = -a. The equation can be used to find the coordinates of other important points on the parabola.
