limit as x approaches-8+of ((x+7))/(x+8)

Lösung

x \to - 8 + lim (\frac{( x + 7 )}{x + 8})

Lösung

- \infty

Schritte zur Lösung

x \to - 8 + lim (\frac{x + 7}{x + 8})

\frac{x + 7}{x + 8} = (x + 7) \frac{1}{x + 8}

= x \to - 8 + lim ((x + 7) \frac{1}{x + 8})

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 - 8 + lim (x + 7) \cdot x \to - 8 + lim (\frac{1}{x + 8})

x \to - 8 + lim (x + 7) = - 1

x \to - 8 + lim (\frac{1}{x + 8}) = \infty

= (- 1) \cdot \infty

Wende die Unendlichkeitseigenschaft an:

- c \cdot \infty = - \infty

= - \infty
