Question

2. Dada a função f(x) = 2 - 2 x + 1, quando x = {1, 2, 3, 4, 5). Determine os valores de f(x) e construa o gráfico
​

Answer 1

f(1) =2-2.1+1
f(1)=2-2+1
f(1)=2-3
f(1)= -1

f(2)= 2-2.2+1
f(2)=2-4+1
f(2)=2-5
f(2)=-3

f(3)= 2-2.3+1
f(3)=2-6+1
f(3)=2-7
f(3)=-5

f(4)=2-2.4+1
f(4)=2-8+1
f(4)=2-9
f(4)=-7

f(5)=2-2.5+1
f(5)=2-10+1
f(5)=2-11
f(5)=-9
