Considere os conjuntos A{1, 3, 5, 7} e B {a, e, i, o} e a função f A --> B. Assinale a função que é Bijetora: a. f1 = {(1, a), (3, e) , (5, i) , (7, o)}. b. f2 = {(1, a) (3, a), (5, a), (7, a)}. c. f3 = {(1, a) (3, b), (5, a), (7, o)}. d. f4 = {(1, a) (3, b), (5, a), (7, a)}. e. f2 = {(1, a) (3, e), (5, a), (7, e)}.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
