limit as x approaches-2 of (x^2-9)/(2-x)

Lösung

x \to - 2 lim (\frac{x ^{2} - 9}{2 - x})

- \frac{5}{4}

Dezimale

- 1.25

Schritte zur Lösung

x \to - 2 lim (\frac{x ^{2} - 9}{2 - x})

Setze den Wert

x = - 2

ein

= \frac{( - 2 ) ^{2} - 9}{2 - ( - 2 )}

Vereinfache

\frac{( - 2 ) ^{2} - 9}{2 - ( - 2 )} : - \frac{5}{4}

= - \frac{5}{4}

x \to 5 lim ((5 - x)^{x - 5})

x \to 3 - lim (\frac{x - 5}{x ^{2} - 9})

x \to - 2 lim (\frac{2 x}{4 - x ^{2}})

n \to 1 lim (ln (n))

x \to 0 lim (3 - 2 x - x^{2})
