domain of f(x)=(-13)/((4+x)^2)

domain

f (x) = \frac{- 13}{( 4 + x ) ^{2}}

x < - 4 or x > - 4

Interval Notation

(- \infty, - 4) \cup (- 4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 4

The function domain

x < - 4 or x > - 4

\frac{x ^{2} + x - 20}{5 x + 25}

20 x + 7 y = 19

7 y = 1

f (x) = 4^{x + 1} - 5

What is the domain of f(x)=(-13)/((4+x)^2) ?
The domain of f(x)=(-13)/((4+x)^2) is x<-4\lor x>-4
