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

domain of f(x)= 1/(sqrt(1.5x-6.2x^2))domain

f (x) = \frac{1}{1.5 x - 6.2 x ^{2}}

domain of f(x)=ln(3x-6)domain

f (x) = ln (3 x - 6)

domain of (x-5)^2 domain

(x - 5)^{2}

domain of f(x)=(x^2-2x+1)/((x+2)(x+1))domain

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

domain of sqrt(4-x^4)domain

4 - x^{4}
