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 positive quantity approaching 0 from the right

= - \infty

x \to 7 lim (\frac{5}{x - 7})

\frac{d}{d x} ((y) x^{2})

\frac{\partial}{\partial x} (x z t^{2} y + 1)

f (x) = e^{3 e^{x}}

(5.4) 8 x^{2} - 9 y^{3} = - 376
