limit as x approaches 2-of 2-1/(x-2)

解

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

解

\infty

解答ステップ

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

x \to a lim [f (x) \pm g (x)] = x \to a lim f (x) \pm x \to a lim g (x)

不定形式の場合を除く

= x \to 2 - lim (2) - x \to 2 - lim (\frac{1}{x - 2})

x \to 2 - lim (2) = 2

x \to 2 - lim (\frac{1}{x - 2}) = - \infty

= 2 - (- \infty)

簡素化

2 - (- \infty) : \infty

= \infty
