Schritte zur Lösung

x \to \infty lim (\frac{4 x + 1}{12 x ^{2} - 7})

Teile durch den größten gemeinsamen Potenznenner:

\frac{\frac{4}{x} + \frac{1}{x ^{2}}}{12 - \frac{7}{x ^{2}}}

= x \to \infty lim (\frac{\frac{4}{x} + \frac{1}{x ^{2}}}{12 - \frac{7}{x ^{2}}})

x \to a lim [\frac{f ( x )}{g ( x )}] = \frac{lim _{x \to a} f ( x )}{lim _{x \to a} g ( x )}, x \to a lim g (x) \neq = 0

mit Einschränkung des unbestimmten Ausdrucks

= \frac{lim _{x \to \infty} ( \frac{4}{x} + \frac{1}{x ^{2}} )}{lim _{x \to \infty} ( 12 - \frac{7}{x ^{2}} )}

x \to \infty lim (\frac{4}{x} + \frac{1}{x ^{2}}) = 0

x \to \infty lim (12 - \frac{7}{x ^{2}}) = 12

= \frac{0}{12}

Wende Regel an

\frac{0}{a} = 0, a \neq = 0

= 0
