Solution

domain

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

Solution

x < 0 or x > 0

+1

Interval Notation

(- \infty, 0) \cup (0, \infty)

Solution steps

Find undefined (singularity) points:

x = 0

The function domain

x < 0 or x > 0

Popular Examples

domain of f(x)=(x+1)/(x+3)domain

f (x) = \frac{x + 1}{x + 3}

domain of f(x)=log_{10}(7-x)domain

f (x) = lo g_{10} (7 - x)

domain of f(x)=e^{3-2x}domain

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

domain of f(x)=x(16-x)(18-4x)domain

f (x) = x (16 - x) (18 - 4 x)

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

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