domain of (x^2+1)/x

Solution

domain

\frac{x ^{2} + 1}{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)=sqrt(((x+1)(x-1))/x)domain

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

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

(x + 2)^{2} (x - 1)

asymptotes of f(x)=(x^3)/((1+x)^2)asymptotes

f (x) = \frac{x ^{3}}{( 1 + x ) ^{2}}

inverse of f(x)= 1/2 (x-1)^3+3 inverse

f (x) = \frac{1}{2} (x - 1)^{3} + 3

inflection y=x^3+3x^2+3x+2 inflection points

y = x^{3} + 3 x^{2} + 3 x + 2
