domain of f(x)=(6x)/(x+2)

domain

f (x) = \frac{6 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) = - 5 x^{3} + 25 x^{2} + 15

g (x) = x - 25

y = - 7 x + 21

(\frac{16}{3}, \frac{1}{5}), (\frac{1}{3}, \frac{6}{5})

- 3 sin (x - \frac{π}{4})

What is the domain of f(x)=(6x)/(x+2) ?
The domain of f(x)=(6x)/(x+2) is x<-2\lor x>-2
