The general equation is. y ′ = m x ′ 2. where y ′ and x ′ are coordinates of a point in a rotated and transalted coordinate system. The good news is that if you're willing to write a point ( x, y) as a vector v = [ x y 1], then the equation of a general parabola is just. v t M v = 0. where M is the matrix.
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) Web3 de fev. de 2024 · Types of Parabolas.
