f(x) = (x-1)/2x
Asimptote verticale
lim x-> 0 f(x) = (x-1)/2x = -1/0₊ = +infinit
lim x-> 0 f(x) = (x-1)/2x = -1/0₋ = -infinit
Functia are as. verticale pe dreapta x=0
As. orizontale
lim x-> -inf f(x) = (x-1)/2x = x(1-1/x) /2x = 1/2
lim x-> +inf f(x) = (x-1)/2x = x(1-1/x) /2x = 1/2
Functia are as. orizontale pe dreapta y = 1/2
As. oblice nu are intrucat functia are deja asimptote orizontale
