limit as x approaches infinity of 7/x-9

解

x \to \infty lim (\frac{7}{x} - 9)

解

- 9

解答ステップ

x \to \infty lim (\frac{7}{x} - 9)

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 \infty lim (\frac{7}{x}) - x \to \infty lim (9)

x \to \infty lim (\frac{7}{x}) = 0

x \to \infty lim (9) = 9

= 0 - 9

簡素化

= - 9
