domain of (x-4)/(x^2-16)

domain

\frac{x - 4}{x ^{2} - 16}

x < - 4 or - 4 < x < 4 or x > 4

Interval Notation

(- \infty, - 4) \cup (- 4, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = 4, x = - 4

The function domain

x < - 4 or - 4 < x < 4 or x > 4

f (x) = \frac{- 5 x - 6}{- 15 x - 28}

\frac{1}{x - 2}

\frac{x - 3}{x - 6}

- 3 cos (4 x)

x^{5} + 5 x^{4}
