domain of f(x)=(9x)/(x+2)

domain

f (x) = \frac{9 x}{x + 2}

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

f (x) = (- 1.4)

\frac{5 x - 3}{2 x + 3}

\frac{3 x - 4}{5 x + 6}

f (x) = \frac{( 10 + ∣ x ∣ )}{x}

2 (x + 1) + 4

What is the domain of f(x)=(9x)/(x+2) ?
The domain of f(x)=(9x)/(x+2) is x<-2\lor x>-2
