Question

6) Considere a função f(x) = -2x + 1. O valor de f(0)+ f(2)+ f(-1) + f(5)
A)8
B)-8
C)20
D)12

Answer 1

$F(0)= -2\times 0 + 1\\ F(0)= 1\\ F(2)=-2 \times 2+1\\F(2)= -4+1= -3\\ F(-1)= --2\times -1 +1\\ F(-1)= 2+1\\ F(-1)= 3\\ F(5)= -2\times 5+1\\ F(5)= -10+1\\ F(5)= -9$

$F(0)+F(2)+F(-1)+f(5)\\ 1+(-3)+3 -9\\ = -8$
