About Quadratic Functions

A quadratic function y = ax² + bx + c graphs as a parabola. If a > 0, the parabola opens upward with a minimum at the vertex. If a < 0, it opens downward with a maximum.

The vertex is the turning point at x = -b/(2a). The roots(where y = 0) are found using the quadratic formula: x = (-b ± √(b²-4ac)) / (2a). The discriminant b²-4ac tells you: positive = 2 real roots, zero = 1 root (touches axis), negative = no real roots.

Graphing parabolas is essential for SAT Math (quadratic models, vertex form),JEE Main (conic sections, quadratic equations), andCBSE Class 10 (quadratic equations chapter).
