HELP: Limit of absolute value

  1. Sep 26, 2004 #1
    Compute the limit of: (absolute value)

    f(x) = 4 (absolute value of x + 4) / (x+4)

    as x approaches -4 from the right.

    I got 4 because x>-4. Am I right?

    Yep that's correct! When [tex]x > 4, |x + 4| = x + 4[/tex]

    [tex]lim_{x \rightarrow -4^+} f(x) = lim_{x \rightarrow -4^+} 4\frac{x+4}{x+4} = 4[/tex]
