domain of 4/(x^2-1)

Solution

domain

\frac{4}{x ^{2} - 1}

Solution

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

+1

Solution steps

Find undefined (singularity) points:

x = 1, x = - 1

The function domain

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

Popular Examples

parity f(x)=(2x^4+5x+5)/(5x^4+4x-2)parity

f (x) = \frac{2 x ^{4} + 5 x + 5}{5 x ^{4} + 4 x - 2}

asymptotes of (x^3+3)/x asymptotes

\frac{x ^{3} + 3}{x}

range of f(x)= 2/(x+1)range

f (x) = \frac{2}{x + 1}

domain of f(x)=(3x)/(x+3)domain

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

parity f(x)=|x|+4 parity

f (x) = ∣ x ∣ + 4
