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

domain

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

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

2 x^{3} - 24 x

f (x) = - 7 x + 3

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

y = - 5 x - e^{- 5 x}

f (x) = - 4 x - 5

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