domain of f(x)=-7/((3+x)^2)

domain

f (x) = - \frac{7}{( 3 + x ) ^{2}}

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

- ∣ x + 4 ∣ - x

- 3 sin (2 x) - 4

\frac{x - 4}{x - 8}

\frac{4 - x}{2 x - 3}

f (x) = \frac{x - 4}{x ^{2} - 11 x + 28}

What is the domain of f(x)=-7/((3+x)^2) ?
The domain of f(x)=-7/((3+x)^2) is x<-3\lor x>-3
