domain of y=-1/x

Solution

domain

y = - \frac{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)=(ln(x+1))/(x-sqrt(3+2x))domain

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

domain of g(x)=(x-4)/3 domain

g (x) = \frac{x - 4}{3}

domain of f(x)=sqrt(x^2-9)+sqrt(4-x)domain

f (x) = x^{2} - 9 + 4 - x

domain of f(x)=ln(x^2+9)domain

f (x) = ln (x^{2} + 9)

domain of f(x)=\sqrt[10]{x-1}domain
