Jimmy Chang, a math expert, explains the concept of range in mathematics, often discussed alongside domain. The range is the set of Y values resulting from plugging X values into a function. He provides examples using ordered pairs, linear functions, and square root functions to illustrate how to determine the range. For linear functions, the range can be all real numbers, while for square root functions, the range is limited to non-negative numbers.
