Introduction to Quadratic Functions and Graphs

The video tutorial introduces quadratic equations, defining them as expressions where the highest power of the variable is 2. It explains the standard form of a quadratic equation and the roles of coefficients a, b, and c. The tutorial covers graphing quadratics, identifying positive and negative shapes, and finding roots. It also discusses the effects of changing coefficients on the graph's shape and position. The video concludes with a summary of key concepts and encourages further assessments.

What is the significance of the roots of a quadratic equation?

How do changes in the coefficient 'c' affect the graph of a quadratic function?

How does changing the coefficient 'a' affect the shape of the quadratic graph?
