How to solve a parabola
WebOct 6, 2024 · Key Concepts. A parabola is the set of all points (x,y) in a plane that are the same distance from a fixed line, called the directrix, and a fixed point (the focus) not on the directrix. The standard form of a parabola with vertex (0,0) and the x -axis as its axis of symmetry can be used to graph the parabola. WebAxis: Negative y-axis. Thus, we can derive the equations of the parabolas as: y 2 = 4ax. y 2 = -4ax. x 2 = 4ay. x 2 = -4ay. These four equations are called standard equations of parabolas. It is important to note that the standard equations of parabolas focus on one of the coordinate axes, the vertex at the origin.

WebNov 9, 2024 · We can see from the graph that the parabola intersects the x-axis (the line y = 0) at x = 2 and x= 6. At this point, we know that the solutions of the equation are x = 2 and x = 6. However, we can find the quadratic equation as well. First, the quadratic factored form looks like this: y = a (x – r) (x – s)
