domain of f(x)= 2/(3x+12)

domain

f (x) = \frac{2}{3 x + 12}

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

f (x) = 5 - 2 x

y = 9 - x^{2}

x^{2} + 1

3 (x + 1) (x - 2)

\frac{4 x - 3}{6 - 2 x}

What is the domain of f(x)= 2/(3x+12) ?
The domain of f(x)= 2/(3x+12) is x<-4\lor x>-4
