limit as x approaches 0-of 9/x-9/(|x|)

x \to 0 - lim (\frac{9}{x} - \frac{9}{∣ x ∣})

- \infty

Solution steps

x \to 0 - lim (\frac{9}{x} - \frac{9}{∣ x ∣})

x

is negative when

x \to 0 -

. Therefore

∣ x ∣ = - x

= x \to 0 - lim (\frac{9}{x} - \frac{9}{- x})

x \to a lim [f (x) \pm g (x)] = x \to a lim f (x) \pm x \to a lim g (x)

With the exception of indeterminate form

= x \to 0 - lim (\frac{9}{x}) - x \to 0 - lim (\frac{9}{- x})

x \to 0 - lim (\frac{9}{x}) = - \infty

x \to 0 - lim (\frac{9}{- x}) = \infty

= - \infty - \infty

Apply Infinity Property:

- \infty - \infty = - \infty

= - \infty
