Resposta :
Resposta:1.a) F(0) = 2 - 4×0
F(0) = 2 - 0
F(0) = 2
b) F(-1) = 2 - 4×(-1)
F(-1) = 2 + 4
F(-1) = 6
c) F(1/5) = 2 - 4×(1,5)
F(1/5) = 2 - 6
F(1/5) = - 4
d) F(-1/5) = 2 - 4×(-1,5)
F(-1/5) = 2 + 6
F(-1/5) = 8
2. a) F(0) = -4×(0) + 1
F(0) = -4 + 1
F(0) = -3
b) F(6) = -4×(6) + 1
F(6) = - 24 + 1
F(6) = - 23
c) F(- 1/2) = -4×(- 1,2) + 1
F(- 1/2) = + 4,8 + 1
F(- 1/2) = 5,8
