A function graph is a way to visually represent a mathematical function. It plots points on a coordinate system, where the x-axis and y-axis represent different variables. The points on the graph are determined by substituting various values of the independent variable (often denoted as x) into the function and calculating the corresponding values of the dependent variable (often denoted as y). These points are then connected by a continuous line or curve to form the graph of the function. The shape and behavior of the function graph provide insights into the properties and relationships of the function.
