limit as x approaches-1 of x^2-x+7

Lösung

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

9

Schritte zur Lösung

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

Setze den Wert

x = - 1

ein

= (- 1)^{2} - (- 1) + 7

Vereinfache

(- 1)^{2} - (- 1) + 7 : 9

= 9

d er i v a t i v e f (x) = ln (3 + x)

\frac{d y}{d x} = \frac{y ^{2} + 6 x x ^{2} + y ^{2}}{x y}

t an g e n t f (x) = 2 (x^{2} - 1)^{3}, at x = 2

x \to - 8 + lim (\frac{2 x}{x + 8})

d er i v a t i v e f (x) = \frac{2}{4 x + 3}
