Solution

domain

\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

extreme f(x)=x^2-9 extreme points

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

symmetry y=x^2-2x-63 symmetry

y = x^{2} - 2 x - 63

inflection f(x)=x^3+12x+5 inflection points

f (x) = x^{3} + 12 x + 5

inverse of f(x)=6^x inverse

f (x) = 6^{x}

midpoint (0,5),(-2, 1/3)midpoint

(0, 5), (- 2, \frac{1}{3})
