Question

Seja a função f(x) = (x/2) – 2 :

a) Calcular f(-2) b) Calcular f(1/2) c) Calcular f(0)

Answer 1

Respostas:

a) -3

b) -1,75

c) -2

Explicação:

a) f(x)=( x/2)-2

f(-2)=(-2/2)-2

f(-2)=(-1)-2

f(-2) = (-3)

b) f(x)=(x/2)-2

f(1/2)=( (1/2)/2)-2

f(1/2)=(0,5/2)-2

f(1/2)=(0,25)-2

f(1/2)=(-1,75)

c) f(x)=(x/2)-2

f(0)=(0/2)-2

f(0)=0-2

f(0)= -2
