What is the function form of an equasion?

The function form of an equation typically expresses a relationship between variables, usually in the format ( y = f(x) ), where ( y ) is the dependent variable, ( x ) is the independent variable, and ( f(x) ) is a function that defines how ( y ) changes with respect to ( x ). This form can represent linear, quadratic, exponential, and other types of relationships, depending on the specific function used. For example, a linear function takes the form ( y = mx + b ), where ( m ) is the slope and ( b ) is the y-intercept.
