limit as x approaches 7-of (2x+1)/(x-7)

Lösung

x \to 7 - lim (\frac{2 x + 1}{x - 7})

- \infty

Schritte zur Lösung

x \to 7 - lim (\frac{2 x + 1}{x - 7})

\frac{2 x + 1}{x - 7} = (2 x + 1) \frac{1}{x - 7}

= x \to 7 - lim ((2 x + 1) \frac{1}{x - 7})

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 7 - lim (2 x + 1) \cdot x \to 7 - lim (\frac{1}{x - 7})

x \to 7 - lim (2 x + 1) = 15

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

= 15 (- \infty)

Wende die Unendlichkeitseigenschaft an:

c \cdot (- \infty) = - \infty

= - \infty
