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

domain

f (x) = - \frac{9}{( 2 + 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) = \frac{1}{2} x - 2

f (x) = \frac{x - 2}{3 x + 5}

f (x) = - 2

2 x - y = 1

f (x) = \frac{16}{x}

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