domain of (3+x)/x

Solution

domain

\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

f(x)= x/(x^2-1)

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

range of f(x)=(x+2)^2-5 range

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

y = - x - 4

asymptotes of f(x)=(x^2+x-20)/(x-6)asymptotes

f (x) = \frac{x ^{2} + x - 20}{x - 6}

intercepts of y=3*x^2 intercepts

y = 3 \cdot x^{2}
