In the first lecture of Linear Relations and Functions, Dr. Eaton reviews concepts from Algebra 1 such as the coordinate plane, x-coordinate, y-coordinate, coordinate pairs, and quadrants. Next up are relations with domain and range. Functions follow and are shown to be able to be represented with tables and maps. One-to-one functions are investigated next as well as graphs of relations such as discrete examples and continuous examples. Dr. Eaton then shows how to utilize the very important vertical line test used to determine if a relation is a function. Finally are independent variables, dependent variables, and function notation. This lecture is finished off with four complete video examples.
