domain of (3x)/(x+7)

Solution

domain

\frac{3 x}{x + 7}

Solution

x < - 7 or x > - 7

+1

Interval Notation

(- \infty, - 7) \cup (- 7, \infty)

Solution steps

Find undefined (singularity) points:

x = - 7

The function domain

x < - 7 or x > - 7

Popular Examples

domain of f(x)=(2x-3)/(sqrt(3x+3))domain

f (x) = \frac{2 x - 3}{3 x + 3}

domain of ln(4x-5)domain

ln (4 x - 5)

domain of y= 4/(x+1)domain

y = \frac{4}{x + 1}

domain of y=-x^2-2x-3 domain

y = - x^{2} - 2 x - 3

domain of f(x)= x/(x^2+11x+28)domain

f (x) = \frac{x}{x ^{2} + 11 x + 28}
