Solution

domain

f (x) = x^{- 2}

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)= 3/2 x^4-2x^3-6x^2+8 domain

f (x) = \frac{3}{2} x^{4} - 2 x^{3} - 6 x^{2} + 8

domain of f(x)=(1/7)^x domain

f (x) = (\frac{1}{7})^{x}

domain of (x^3+3x^2-4x)/(-4x^2-4x+24)domain

\frac{x ^{3} + 3 x ^{2} - 4 x}{- 4 x ^{2} - 4 x + 24}

domain of f(x)=(2x-7)/(4x+6)domain

f (x) = \frac{2 x - 7}{4 x + 6}

domain of f(x)=((5x^3-4))/(x^2+2x-15)domain

f (x) = \frac{( 5 x ^{3} - 4 )}{x ^{2} + 2 x - 15}
