Function graph

A function graph is a graphical representation of a mathematical relationship between two variables, usually labeled as 'x' and 'y'. Each point on the graph shows how one variable (y) changes in response to another (x). For example, in a function that describes how distance changes over time, x could represent time, while y could represent distance. The overall shape of the graph can reveal important information, such as trends and patterns. By analyzing the graph, one can understand how different inputs affect the output, making it a valuable tool in mathematics and various real-life applications.
