WebOct 6, 2024 · Graph: Solution: 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) WebInteractive, free online graphing calculator from GeoGebra: graph functions, plot data, drag sliders, and much more!
