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

domain

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

x < - 5 or x > - 5

Interval Notation

(- \infty, - 5) \cup (- 5, \infty)

Solution steps

Find undefined (singularity) points:

x = - 5

The function domain

x < - 5 or x > - 5

\frac{x}{x + 9}

f (x) = ln (e + x^{2})

y = 2 x + 1

f (x) = \frac{4 x}{x - 2}

f (x) = x^{3} - 36 x

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