domain of 1/(x^2-1)

Solution

domain

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

Solution

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

+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

Popular Examples

inverse of f(x)= 1/(x+10)inverse

f (x) = \frac{1}{x + 10}

inverse of f(x)=(16)/(5+3x)inverse

f (x) = \frac{16}{5 + 3 x}

asymptotes of f(x)=(6-3x)/(x-8)asymptotes

f (x) = \frac{6 - 3 x}{x - 8}

domain of-sqrt(x+2)domain

- x + 2

domain of f(x)=(x-3)^2 domain

f (x) = (x - 3)^{2}
