Question

Considere a função f,dada por: f(x) = 4x +3.calcule: f (0)+f (-1)+f (1)/f (5)+f (6)

Answer 1

Essa questão é muito trabalho e pouco pensamento . Basta nós substuirmos o "x" na lei de formação pelo valor em parenteses ( EX : f(0) => substitua x por 0 na lei de formação e resolva o cálculo ) .
f(0) + f(-1) + f(1)
---------------------                                                                                                           f(5) + f(6)                                                                                                                                                  
3 - 1 + 7                                                                                                                           -----------                                                                                                                           23 + 27
