domain of f(x)=(5x)/(x+3)-3

domain

f (x) = \frac{5 x}{x + 3} - 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

14 x + 6 y = 36

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

f (x) = 6 lo g_{5} (- 4 x) - 7

3 x + 18

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

What is the domain of f(x)=(5x)/(x+3)-3 ?
The domain of f(x)=(5x)/(x+3)-3 is x<-3\lor x>-3
