Graph of a function

The graph of a function is a visual representation of the relationship between the inputs (independent variables) and outputs (dependent variables) of that function. In coordinate geometry, a function can often be represented in a two-dimensional space using a Cartesian coordinate system, where the x-axis represents the independent variable (often denoted as \( x \)) and the y-axis represents the dependent variable (often denoted as \( f(x) \) or \( y \)).
