Understanding Piecewise Defined Functions

This video tutorial explains how to analyze a piecewise defined function by examining its graph. It covers determining the domain and range using interval notation, evaluating specific function values, and identifying intercepts and zeros. The tutorial also discusses finding the minimum and maximum values of the function and analyzing its behavior over different intervals, such as increasing, decreasing, or constant.

What is the domain of the piecewise defined function in interval notation?

• [-3, 5)

• (-3, 5)

• [-3, 5]

• (-3, 5]
