Domínio de Funções de Várias Variáveis: GRÁFICO DO DOMÍNIO #4

Domain of functions of two variables Domain of a function of two variables, graph of the domain Introduction to Functions of Two Variables A function of two variables is a rule that associates to each ordered pair of real numbers (x,y) of a domain D a single real value, denoted by f(x,y). The set D is called the domain of f and its range is the set of all possible values ​​of f, that is, {f(x,y):(x,y) ∈ D}.
