You need more than one tangent to find the equation of a parabola.
Look at the discriminant, B2 - 4AC, in the quadratic equation. As it goes from negative to positive, the parabola moves in the direction of its small end towards the X-axis. At zero, it touches the X-axis.

Down
Finding the vertex of the parabola is important because it tells you where the bottom (or the top, for a parabola that 'opens' downward), and thus where you can begin graphing.
A parabola equation cannot be answered since it is not a question!
If you have the equation in the form y = ax^2 + bx + c (where "^2" means squared), if "a" is positive, the parabola opens upwards; otherwise it opens downwards.

An equation that when plotted produces a parabola is a quadratic equation of the form y = ax2 + bx + c where a, b and c are constants.
An equation for a parabola always has some type of irregular variable, usually a squared variable or higher.
The answer depends on the form in which the equation of the parabola is given. For y^2 = 4ax the directrix is x = -2a.

The given terms can't be an equation without an equality sign but a negative parabola opens down wards whereas a positive parabola opens up wards.
The equation does not represent that of a parabola.
If the equation of the parabola isy = ax^2 + bx + c, then it opens above when a>0 and opens below when a<0. [If a = 0 then the equation describes a straight line, and not a parabola!].
