Question

2- Considerando a função f(x) = x/x²+1, calcule: a) f (3)=
b) f (0)=
c) f (1)=
d) f (2)=
e) f (3/10)=

OBS: Preciso das contas e o resultado completo

Answer 1

Oi 

f(x) = x/(x² + 1)

a) f(3) = 3/(9 + 1) = 3/10

b) f(0) = 0/(0 + 1) = 0

c) f(1) = 1/(1² + 1) = 1/2

d) f(2) = 2/(2² + 1) = 2/5

e) f(3/10) = (3/10)/(9/100 + 1) = (3/10)/(109/100) = 30/109
