Sejam f : R- {3} -> R – {-2} e g: R – {-2} -> R – {3}
Sejam f : R- {3} -> R – {-2} e g: R – {-2} -> R – {3} duas funções tais que f(g(x))=x, para todo x no domínio de g. Se g(x)= 3x+1/x+2 calcule f(2).
Estou estudando para o enem e parei justamente nessa pergunta por não lembrar de como fazer… se for assim p(2)= 3x+1/x+2 … eu sinceramente não lembro…
