Web17 de abr. de 2024 · Since a = 1, the parabola opens upward. Furthermore, c = −1, so the y -intercept is (0, −1). To find the x -intercepts, set y = 0. In this case, solve using the quadratic formula with a = 1, b = −2, and c = −1. Here we obtain two real solutions for x, and thus there are two x -intercepts: (1 − √2, 0) and (1 + √2, 0) WebThe parabola equation is simplest if the vertex is at the origin and the axis of symmetry is along the x-axis and y-axis. The four such possible orientations of the parabola are …

WebThe distance between the vertex and the focus, measured along the axis of symmetry, is the "focal length". The "latus rectum" is the chord of the parabola that is parallel to the directrix and passes through the focus. Parabolas can open up, down, left, right, or in some other arbitrary direction.
WebParabola equation from focus and directrix Given the focus and the directrix of a parabola, we can find the parabola's equation. Consider, for example, the parabola whose focus is at (-2,5) (−2,5) and directrix is y=3 y = 3. We start by … how many moles of n are in 10 mol of mg no3 2WebThe given focus of the parabola is (a, 0) = (4, 0)., and a = 4. For the parabola having the x-axis as the axis and the origin as the vertex, the equation of the parabola is y 2 = 4ax. Hence the equation of the parabola is y 2 = 4 (4)x, or y 2 = 16x. Therefore, the equation of the parabola is y 2 = 16x.
