domain of (x-3)/(x^2-1)

domain

\frac{x - 3}{x ^{2} - 1}

x < - 1 or - 1 < x < 1 or x > 1

Interval Notation

(- \infty, - 1) \cup (- 1, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = 1, x = - 1

The function domain

x < - 1 or - 1 < x < 1 or x > 1

\frac{36 - x ^{2}}{x + 3}

\frac{s}{s ^{2} - 16}

f (x) = 2 - x

(x - 14)^{2}

f (x) = \frac{1 - e ^{- x}}{1 + e ^{- x}}
