Question

Dada a função afim f(x) = 2X – 2,
determine:
a) f(-2)=
b) f(-1) =
c) f(0=
d) f(1)=
e) f(2) =

Answer 1

Resposta:

a) -6

b) -4

c) -2

d) 0

e)2

Explicação passo-a-passo:

a) f(-2)= 2.(-2) -2

f(-2)= -4-2

f(-2)= -6

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

f(-1) = -2-2

f(-1) = -4

c) f(0) = 2.0-2

f(0) = 0 - 2

f(0) = -2

d) f(1) = 2.1-2

f(1) = 2-2

f(1) = 0

e) f(2) = 2.2-2

f(2) = 4-2

f(2) = 2
