domain of (x-5)/(x^2-16)

domain

\frac{x - 5}{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{2 x ^{2} + x - 3}{3 x - 9}

(8.4) (10.2)

10 e^{- x} + 4

f (x) = x^{2} - 2 x + 1

\frac{t - 1}{t + 1}
