Explaining The Universe on Instagram: "A parabola is a U-shaped curve that appears when you graph a quadratic function, and it can open upward, downward, or sideways depending on its orientation. Mathematically, a parabola is the set of all points that are the same distance from a fixed point, called the focus, and a fixed line, called the directrix. The midpoint between the focus and directrix is the vertex, which is the point where the parabola changes direction. • #explore #reels #viral #univ
