domain of (3x+9)/x

Solution

domain

\frac{3 x + 9}{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)= 1/(ln|x^2-1|)domain

f (x) = \frac{1}{ln ∣ x ^{2} - 1 ∣}

inverse of f(x)=(x+2)/(2x-1)inverse

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

domain of f(x)=sqrt(x^2+2x-8)domain

f (x) = x^{2} + 2 x - 8

domain of f(x)=\sqrt[5]{x}domain

domain of f(x)= 3/(sqrt(1-3x))domain

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