Quadratic Functions
- The discriminant of a quadratic function determines the number of x-intercepts and the nature of the roots (real or complex).
- The standard form of a quadratic function is ax^2 + bx + c, where a, b, and c are constants, and a ≠ 0.
- A quadratic function can have a maximum of 2 x-intercepts, as it is a degree 2 polynomial equation.
