Question

1) Dada a função f(x) = 2x + 1, determine f (-2), f (-1), f (0), f (1):

Answer 1

Resposta:

Explicação passo-a-passo:

f(x) = 2x + 1

f(-2) = 2.(-2) + 1 => -4 + 1 = -3

f(-1) = 2.(-1) + 1 => -2 + 1 = -1

f(0) = 2.(0) + 1 => 0 + 1 = 1

f(1) = 2.(1) + 1 => 2 + 1 = 3

Answer 2

Resposta:

f(×)=2×+1

f(-2)=2.(-2)+1

f(-2)=-4+1

f(-2)=-3

f(×)=2×+1

f(-1)=2.(-1)+1

f(-1)=-2+1

f(-1)=-1

f(×)=2×+1

f(0)=2.0+1

f(0)=0+1

f(0)=1

f(×)=2×+1

f(1)=2.1+1

f(1)=2+1

f(1)=3
