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

Lösung

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

- \infty

Schritte zur Lösung

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

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

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

x \to - 3 + lim (4 x + 3) = - 9

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

= (- 9) \cdot \infty
