domain of f(x)= 6/(x+9)

domain

f (x) = \frac{6}{x + 9}

x < - 9 or x > - 9

Interval Notation

(- \infty, - 9) \cup (- 9, \infty)

Solution steps

Find undefined (singularity) points:

x = - 9

The function domain

x < - 9 or x > - 9

(2 - x)^{2} - 4

(10.6) (4.2)

y = \frac{3 x + 2}{x + 5}

f (x) = 4 x^{3} - 12 x

What is the domain of f(x)= 6/(x+9) ?
The domain of f(x)= 6/(x+9) is x<-9\lor x>-9
