Question

Construa o gráfico das seguintes funções afins:

a) y= x+2

b) y= 2x+2

c) y= 6-3x

d) y= 1-x

Alguém me ajudar!

Answer 1

a)
f(-2) = -2+2 = 0
f(-1) = -1+2 = 1
f(0) = 0+2 = 2
f(1) = 1+2 = 3
f(2) = 2+2 = 4

b)
f(-2) = 2.(-2)+2 = -2
f(-1) = 2.(-1)+2 = 0
f(0) = 2.0+2 = 2
f(1) = 2.1+2 = 4
f(2) = 2.2+2 = 6

c)
f(-2) = 6-3.(-2) = 12
f(-1) = 6-3.(-1) = 9
f(0) = 6-3.0 = 6
f(1) = 6-3.1 = 3
f(2) = 6-3.2 = 0

d)
f(-2) = 1-(-2) = 3
f(-1) = 1-(-1) = 2
f(0) = 1-0 = 1
f(1) = 1-1 = 0
f(2) = 1-2 = -1
