Opening of parabola formula
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) Web27 de mar. de 2024 · Parabolas and the Distance Formula.
