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

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

\infty

Solution steps

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

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

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

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

With the exception of indeterminate form

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

x \to - 2 - lim (x + 4) = 2

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

= 2 \cdot \infty

Apply Infinity Property:

c \cdot \infty = \infty

= \infty
