What is the domain and range of a quadratic graph

The video tutorial explains the concepts of domain and range in mathematical functions, focusing on parabolas. It covers how to graph parabolas with minimum and maximum values, and discusses the domain as the set of all possible x-values and the range as the set of possible y-values. The tutorial also explores how these concepts apply to specific equations, emphasizing that the domain of parabolas is all real numbers unless constrained, while the range depends on the graph's orientation and vertex.
