Graph of a Mathematical Function
The graph of a mathematical function is the visual representation of all its ordered pairs on a coordinate system. Because a function can be written using function notation where , these ordered pairs can equivalently be expressed as . In this notation, represents the name of the function, is the -coordinate of the ordered pair (the input), and is the corresponding -coordinate (the output). Thus, graphing a relation like produces the exact same line as graphing ; only the notation has changed.
