limit as x approaches 3-of (x+3)/(x-3)

x \to 3 - lim (\frac{x + 3}{x - 3})

- \infty

Solution steps

x \to 3 - lim (\frac{x + 3}{x - 3})

\frac{x + 3}{x - 3} = (x + 3) \frac{1}{x - 3}

= x \to 3 - lim ((x + 3) \frac{1}{x - 3})

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 3 - lim (x + 3) \cdot x \to 3 - lim (\frac{1}{x - 3})

x \to 3 - lim (x + 3) = 6

x \to 3 - lim (\frac{1}{x - 3}) = - \infty

= 6 (- \infty)

Apply Infinity Property:

c \cdot (- \infty) = - \infty

= - \infty
