domain of f(x)= 9/x

Solution

domain

f (x) = \frac{9}{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 g(x)=(x^2)/(x-4)domain

g (x) = \frac{x ^{2}}{x - 4}

inverse of f(x)= 1/2 x+6 inverse

f (x) = \frac{1}{2} x + 6

intercepts of f(x)=(3x^2)/(x^2-16)intercepts

f (x) = \frac{3 x ^{2}}{x ^{2} - 16}

inverse of f(x)=x^2-8x+16 inverse

f (x) = x^{2} - 8 x + 16

domain of f(x)=(2x^2-x-6)/(x^2+9)domain

f (x) = \frac{2 x ^{2} - x - 6}{x ^{2} + 9}
