limit as x approaches 4-of-1/(x^2-16)

解

x \to 4 - lim (- \frac{1}{x ^{2} - 16})

解

\infty

解答ステップ

x \to 4 - lim (- \frac{1}{x ^{2} - 16})

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

= - x \to 4 - lim (\frac{1}{x ^{2} - 16})

左側から

4

に近づく

x

の場合は,

x < 4 \Rightarrow x^{2} - 16 < 0

分母は左から0に近づく負の数量

= - (- \infty)

簡素化

= \infty
