info@snapandsolve.comThe vertex form of a quadratic equation is y = ax^2 + bx + c, where the vertex is at x = -b/(2a). For these equations, b = 0, so the vertex is at x = 0, and the y-coordinate is simply the constant term.
The equation with the more positive y-coordinate of its vertex is c: y = -2x^2, with a vertex y-coordinate of 0.
