Parabola - Wikipedia

A parabola is the U-shaped curve of a quadratic function. Learn how to find the focus, directrix, vertex, axis of symmetry, eccentricity and zeros of a parabola using standard and vertex form. See examples of parabola graph and how to sketch a parabola.

When graphing parabolas, find the vertex and y-intercept. If the x-intercepts exist, find those as well. Also, be sure to find ordered pair solutions on either side of the line of symmetry, \(x=\frac{-b^{2}}{a}\). Use the leading coefficient, a, to determine if a parabola opens upward or downward. If a is positive, then it opens upward.

The equation of a (vertical) parabola with vertex (h, k) and focal length | p | is. (x − h)2 = 4p(y − k). If p > 0, the parabola opens upwards; if p < 0, it opens downwards. Notice that in the standard equation of the parabola above, only one of the variables, x, is squared.

What are parabolas, their equations, their rules? | Purplemath

Section 4.2 : Parabolas. In this section we want to look at the graph of a quadratic function. The most general form of a quadratic function is, \[f\left( x \right) = a{x^2} + bx + c\] The graphs of quadratic functions are called parabolas. Here are some examples of parabolas.
