Parabola graph: It is established that the axis of a parabola passes through the points determined by its focus and its vertex. If the axis is horizontal both focus and vertex have equal ordinates (y-value). The equation is of the form {eq}(y-k)^2=4p(x-h) {/eq}. ...

A parabola is a curved line that is defined by a set of points, each of which are the same distance from a fixed point called the focus and a fixed line called the directrix. It can be used to model many real-world phenomena, from projectiles to satellite dishes. Let’s dive into ...

The parabola starts right at the one-minute mark.)In algebra, dealing with parabolas usually means graphing quadratics or finding the max/min points (that is, the vertices) of parabolas for quadratic word problems. In the context of conics, however, there are some additional considerations.What...
