Pembahasan Karena hanya suku- x yang dikuadratkan, maka grafik dari persamaan tersebut berbentuk parabola vertikal. In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point (the focus) and a line (the directrix). The focus does not lie on the This calculator will find either the equation of the parabola from the given parameters or the axis of symmetry, eccentricity, latus rectum, length of the latus rectum, focus, vertex, directrix, focal parameter, x-intercepts, y-intercepts of the entered parabola.

A parabola is an open curve having one focus and directrix, whereas a hyperbola is an open curve with two branches having two foci and directrices. The eccentricity of a parabola is one, whereas the eccentricity of a hyperbola is greater than one. A parabola is formed when the plane intersects a cone along its slant height.

$\begingroup$ See the related question "Is $\sqrt{x/a}+\sqrt{y/b}=1$ the equation of a parabola tangent to the coordinate axes?". The question itself is not quite a duplicate, as it doesn't ask about various elements of the parabola; however, my answer identifies the focus … Every parabola has a point inside the curve called the focus and a line outside the curve called the directrix.Each point on the parabola is equidistant from the focus and directrix.

En parabel definieras av att det för varje punkt (P) som utgör del av parabeln gäller att avståndet från denna punkt till en  punkt (brännpunkten eller fokus) och till en given rät linje (styrlinjen) är lika. även i en del andra språk, till exempel tyska Parabole och engelska parabola. Det finns emellertid en geometrisk definition av en parabola, som totaliteten av alla punkter vars avstånd från en given punkt ( en parabolas fokus ) är lika med  Fokus (geometri) - Focus (geometry). Från Wikipedia, den fria encyklopedin. Punkt F är en fokuspunkt för röd ellips, grön parabola och blå hyperbola.
