a. oblica y=mx+n
m=[tex] \lim_{nxto \infty} \frac{f(x)}{x} [/tex]
n=[tex] \lim(_{x \to \infty} f(x)-mx) [/tex]
b, orizontala
y=a asimptota orizontala spre +∞, daca limf(x)=a, x→∞
y=a asimptota orizontala spre -∞, daca limf(x)=a, x→-∞
daca exista asimptota orizontala, nu mai exista asimptota oblica
c. verticala
x=a asimptota verticala spre +∞daca exista limf(x)=+∞, x→a
x=asimptota verticala spre -∞daca exista limf(x)=-∞, x→a
