limit as x approaches 2 of (x-1)/(x^2-4)

解

x \to 2 lim (\frac{x - 1}{x ^{2} - 4})

解

は発散する

解答ステップ

x \to 2 lim (\frac{x - 1}{x ^{2} - 4})

x \to a - lim f (x) \neq = x \to a + lim f (x)

の場合, 限度は存在しない

x \to 2 + lim (\frac{x - 1}{x ^{2} - 4}) = \infty

x \to 2 - lim (\frac{x - 1}{x ^{2} - 4}) = - \infty

= は発散する
