Parabola and its parts
WebThe key features of a parabola are its vertex, axis of symmetry, focus, directrix, and latus rectum. See [link]. When given a standard equation for a parabola centered at the origin, we can easily identify the key features to graph the parabola. A line is said to be tangent to a curve if it intersects the curve at exactly one point.

Dotted vertical line drawn through the vertex y–intercept: where the parabola crosses the y –axis. Written in the form (0, y) Roots (x–intercept (s)): where the parabola crosses or rests on the x –axis.
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. WebA parabola is defined as 𝑦 = 𝑎𝑥² + 𝑏𝑥 + 𝑐 for 𝑎 ≠ 0 By factoring out 𝑎 and completing the square, we get = 𝑎(𝑥 + 𝑏 ∕ (2𝑎))² + 𝑐 − 𝑏² ∕ (4𝑎) With ℎ = −𝑏 ∕ (2𝑎) and 𝑘 = 𝑐 − 𝑏² ∕ (4𝑎) we get 𝑦 = 𝑎(𝑥 − ℎ)² + 𝑘 (𝑥 − ℎ)² ≥ 0 for all 𝑥
