domain of 3/x+9

Solution

domain

\frac{3}{x} + 9

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)=(8x+15)/(x^2+5x)domain

f (x) = \frac{8 x + 15}{x ^{2} + 5 x}

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

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

symmetry y=x^2-5x+6 symmetry

y = x^{2} - 5 x + 6

domain of x-12 domain

x - 12

domain of f(x)=(7z+6)/(z-7)+(7z+3)/(z-7)domain

f (x) = \frac{7 z + 6}{z - 7} + \frac{7 z + 3}{z - 7}
