In this module there is a complete review of the topic of quadratic functions and equations. This module covers four key areas: 1. Definition of a quadratic function; 2. Definition of a quadratic equation; 3. Solving quadratic equations algebraically; 4. Solving quadratic functions graphically.

When a driver slams the brakes on a car, skid marks are created on the road. Accident investigators can measure the length of the skid marks to estimate the speed of the car. This involves using a quadratic function.
