domain of f(x)=(3x)/(x+4)

domain

f (x) = \frac{3 x}{x + 4}

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) = - 2 (x + 3)^{2} - 6

f (x) = \frac{x - 1}{3 x - 2}

\frac{x}{1 + x ^{2}}

f (x) = x^{2} - 5 x - 6

f (x) = \frac{1}{ln ( x + x )}

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