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

Solution

domain

f (x) = x + \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)=-3(a-1)domain

f (x) = - 3 (a - 1)

domain of f(x)=sqrt(-x+3)domain

f (x) = - x + 3

slope ofintercept x+3y-3=0 slope intercept

x + 3 y - 3 = 0

slope ofintercept 0 slope intercept

0

intercepts of f(x)=64-x^2 intercepts

f (x) = 64 - x^{2}
