domain of f(x)= 4/(x+9)

domain

f (x) = \frac{4}{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

f (x) = \frac{3 x ^{3} + 3}{x ^{2} - 3 x - 4}

(- 2, - 4), (3, - 7)

2 x^{2} - \frac{1}{x ^{2}}

\frac{6 x}{x + 5}

f (x) = 80 + x

What is the domain of f(x)= 4/(x+9) ?
The domain of f(x)= 4/(x+9) is x<-9\lor x>-9
