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

Lösung

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

Lösung

\infty

Schritte zur Lösung

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

\frac{x + 3}{x + 2} = (x + 3) \frac{1}{x + 2}

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

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

x \to - 2 + lim (x + 3) = 1

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

= 1 \cdot \infty

Wende die Unendlichkeitseigenschaft an:

c \cdot \infty = \infty

= \infty
