limit as x approaches 0-of 4/x-4/(|x|)

x \to 0 - lim (\frac{4}{x} - \frac{4}{∣ x ∣})

- \infty

Solution steps

x \to 0 - lim (\frac{4}{x} - \frac{4}{∣ x ∣})

x

is negative when

x \to 0 -

. Therefore

∣ x ∣ = - x

= x \to 0 - lim (\frac{4}{x} - \frac{4}{- 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{4}{x}) - x \to 0 - lim (\frac{4}{- x})

x \to 0 - lim (\frac{4}{x}) = - \infty

x \to 0 - lim (\frac{4}{- x}) = \infty

= - \infty - \infty

Apply Infinity Property:

- \infty - \infty = - \infty

= - \infty

\int x (x^{3} + 1) d x

x + 1, 3 - x^{2}

\frac{d y}{d x} + 2 y = 90

x \to 3 lim (sec (\frac{π x}{3}))

\int 4 x - y d x
