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

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

7

Solution steps

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

Plug in the value

x = - 2

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

Simplify

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

= 7

x \to \infty lim (x, x)

x \to - 3 - lim (\frac{2}{x + 3})

x \to 1 lim (\frac{ln ( x )}{4 ^{l n (x)} - x})

x \to 0 + lim (1 + e^{\frac{1}{x}})

x \to 1 lim (∣ 2 x - 2 ∣)
