domain of (9x)/(3-x)

Solution

domain

\frac{9 x}{3 - x}

Solution

x < 3 or x > 3

+1

Interval Notation

(- \infty, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

Popular Examples

extreme f(x)=x^4-7x^3-13x^2 extreme points

f (x) = x^{4} - 7 x^{3} - 13 x^{2}

global f(x)=-x^2+11 global extreme points

f (x) = - x^{2} + 11

inverse of f(x)=(x-8)^7 inverse

f (x) = (x - 8)^{7}

extreme f(x)=(4-3x)^2 extreme points

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

inflection f(x)=5x^3-3x inflection points

f (x) = 5 x^{3} - 3 x
