limit as x approaches-8-of (-2x)/(x+8)

x \to - 8 - lim (\frac{- 2 x}{x + 8})

- \infty

Solution steps

x \to - 8 - lim (\frac{- 2 x}{x + 8})

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

= - 2 \cdot x \to - 8 - lim (\frac{x}{x + 8})

Divide by highest denominator power:

\frac{1}{1 + \frac{8}{x}}

= - 2 \cdot x \to - 8 - lim (\frac{1}{1 + \frac{8}{x}})

For

x

approaching

- 8

from the left

, x < - 8 \Rightarrow 1 + \frac{8}{x} > 0

The denominator is a positive quantity approaching 0 from the right

= - 2 \cdot \infty

Apply Infinity Property:

- c \cdot \infty = - \infty

= - \infty

\int π (x + 2)^{2} d x

f (x) = x + 63, (1, 8)

\int_{0}^{1} t 1 + 4 t^{2} d t

x y^{^{'}} = y + e^{\frac{y}{x}}

x \to 2 lim (- 2)
