Cartesian Plot of a Function
In this lesson, you will learn how to represent a function on a Cartesian plot, including the necessary vocabulary and rules. You'll also learn how to interpret a Cartesian graph to answer questions about a given function, including evaluating and solving for specific inputs and outputs. The lesson emphasizes the importance of clear labeling and scaling of the axes, as well as the use of defined symbols for the input and output variables. Overall, this lesson is an essential foundation for understanding and interpreting graphs in math and science.
Know and understand the rules of representing a function in a Cartesian plot including relevant vocabulary. Understand when a Cartesian plot is indicating a relationship is not functional.

The lesson explains the idea of the Cartesian Coordinate System, where it came from, and what it means to functions. The explanation in this video starts from very basic concepts and builds up the idea of a Cartesian coordinate graph. A couple of really nice plots of real-world functions are included as resources also.
