👉 In mathematics, a quainter is a type of quadratic function that has no real roots. These functions are defined by their standard form: f(x) = ax^2 + bx + c where a, b, and c are constants. Quainters have the following properties: 1. They have a maximum or minimum value at x = ± √(b² - 4ac). 2. They have a vertex at (−½b/2a, f(-½b
