limit as x approaches-3+of (x^2)/(x+3)

Lösung

x \to - 3 + lim (\frac{x ^{2}}{x + 3})

Lösung

\infty

Schritte zur Lösung

x \to - 3 + lim (\frac{x ^{2}}{x + 3})

\frac{x ^{2}}{x + 3} = x^{2} \frac{1}{x + 3}

= x \to - 3 + lim (x^{2} \frac{1}{x + 3})

x \to a lim [f (x) \cdot g (x)] = x \to a lim f (x) \cdot x \to a lim g (x)

mit Einschränkung des unbestimmten Ausdrucks

= x \to - 3 + lim (x^{2}) \cdot x \to - 3 + lim (\frac{1}{x + 3})

x \to - 3 + lim (x^{2}) = 9

x \to - 3 + lim (\frac{1}{x + 3}) = \infty

= 9 \cdot \infty

Wende die Unendlichkeitseigenschaft an:

c \cdot \infty = \infty

= \infty
