Quadratic Functions: Turning Points and Roots

Quadratic functions are polynomial functions of degree two, typically expressed in the form f(x) = ax² + bx + c, where 'a' is not equal to zero. Their graphs are always parabolas, which are symmetrical U-shaped curves. These functions are fundamental in various fields, from physics to engineering, describing phenomena like projectile motion and the shape of suspension bridge cables.
