limit as x approaches 1+of (4x-3)/(x-1)

Lösung

x \to 1 + lim (\frac{4 x - 3}{x - 1})

Lösung

\infty

Schritte zur Lösung

x \to 1 + lim (\frac{4 x - 3}{x - 1})

\frac{4 x - 3}{x - 1} = (4 x - 3) \frac{1}{x - 1}

= x \to 1 + lim ((4 x - 3) \frac{1}{x - 1})

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 1 + lim (4 x - 3) \cdot x \to 1 + lim (\frac{1}{x - 1})

x \to 1 + lim (4 x - 3) = 1

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

= 1 \cdot \infty

Wende die Unendlichkeitseigenschaft an:

c \cdot \infty = \infty
