domain of-(19)/((3+x)^2)

domain

- \frac{19}{( 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

sin (x) - cos (x)

f (x) = t - 25

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

\frac{x ^{2} - 8}{4} + 9 x^{2} + 8

f (x) = 25 - x^{2} + - (x - 2)

What is the domain of-(19)/((3+x)^2) ?
The domain of-(19)/((3+x)^2) is x<-3\lor x>-3
