Solution

domain

\frac{1 + x}{1 - x}

Solution

x < 1 or x > 1

+1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 1

The function domain

x < 1 or x > 1

Popular Examples

domain of f(x)=t^2-sqrt(t^2-4)+(1+2t)domain

f (x) = t^{2} - t^{2} - 4 + (1 + 2 t)

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

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

domain of f(x)=x-5/3 domain

f (x) = x - \frac{5}{3}

domain of f(x)=(3x-5)/(x-2)domain

f (x) = \frac{3 x - 5}{x - 2}

domain of sqrt(3x-21)domain

3 x - 21
