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

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

\infty

Solution steps

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

For

x

approaching

2

from the left

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

The denominator is a negative quantity approaching 0 from the left

= \infty

\int \frac{14 x - 1}{( 4 x + 1 ) ( x - 2 )} d x

\int 2 x cos (- 4 x) d x

\frac{d}{d x} (x + ln (3 x))

\int_{0}^{1} 2 (1 + x)^{6} d x

\int \frac{1}{( x + 1 ) ^{2} ( x - 4 )} d x
