Question

Dada a função f (x) = 1 - 5 x /2, Calcule:

a) f (0)

b) f (1)

c) f (2)

Answer 1

Substitua o X:
F(x) = 1-5.x/2

F(0)=1-5.0/2
=1-5.0
=1

F(1)=1-5.1/2

f(2)= 1-5.2/2
=5

Answer 2

Resposta

f(x)= 1-5x/2

a) f(0)= 1-5*0/2

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

b) f(1)= 1-5*1/2= 1-5/2= 2-5/2=-3/2

c) f(2)= 1-5*2/2= 1-10/2=1-5=-4
