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

domain

f (x) = \frac{2}{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) = 3 x^{2} - 25 x + 42

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

f (x) = 15 + 2 x

y = \frac{2 x ^{2} - 3}{x ^{2} + 1}

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

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