Question

Oie, preciso de ajuda . Dada a função f(x)=4x , determine :

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

Answer 1

A) f(2)=4.2
f(2)=8

B) f(0)=4.0
f(0)=0

C) f(-2)=4.(-2)
f(-2)= -8

D) f(1/2)= 4. (1/2)
f(1/2)= 4/2
f(1/2)= 2

Answer 2

f(2) = 4×2 = 8
f(0) = 4×0 = 0
f(-2) = 4×9-2) = -8
f(1/2) = 4× 1/2 = 4/2 = 2
