domain of (2x)/(x-3)

Solution

domain

\frac{2 x}{x - 3}

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

periodicity of f(x)=cos(5x)periodicity

f (x) = cos (5 x)

inverse of f(x)=x+3 inverse

f (x) = x + 3

range of (12-x-x^2)/(x-3)range

\frac{12 - x - x ^{2}}{x - 3}

intercepts of f(x)=x^2+y-16=0 intercepts

f (x) = x^{2} + y - 16 = 0

asymptotes of (x^2-6x-72)/(x^2-18x+72)asymptotes

\frac{x ^{2} - 6 x - 72}{x ^{2} - 18 x + 72}
