domain of f(x)=(6x-2)/(3x+9)

domain

f (x) = \frac{6 x - 2}{3 x + 9}

x < - 3 or x > - 3

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

\frac{x ^{2} - 25}{x + 3}

cos (x + π)

f (x) = \frac{5}{x ^{3} + 10 x ^{2} + 9 x}

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

f (x) = \frac{x ^{2} - 3}{x ^{3} - 27}

What is the domain of f(x)=(6x-2)/(3x+9) ?
The domain of f(x)=(6x-2)/(3x+9) is x<-3\lor x>-3
