domain of 4/(9+x)

Solution

domain

\frac{4}{9 + x}

Solution

x < - 9 or x > - 9

+1

Interval Notation

(- \infty, - 9) \cup (- 9, \infty)

Solution steps

Find undefined (singularity) points:

x = - 9

The function domain

x < - 9 or x > - 9

Popular Examples

range of (3x^2-18x+24)/(x^2-4x)range

\frac{3 x ^{2} - 18 x + 24}{x ^{2} - 4 x}

domain of f(x)=4cos(x-pi/3)+2 domain

f (x) = 4 cos (x - \frac{π}{3}) + 2

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

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

range of f(x)=x^2-3x-4 range

f (x) = x^{2} - 3 x - 4

extreme f(x)=x^2+((26-2x)^2)/9 extreme points

f (x) = x^{2} + \frac{( 26 - 2 x ) ^{2}}{9}
