domain of-(21)/((5+t)^2)

domain

- \frac{21}{( 5 + t ) ^{2}}

t < - 5 or t > - 5

Interval Notation

(- \infty, - 5) \cup (- 5, \infty)

Solution steps

Find undefined (singularity) points:

t = - 5

The function domain

t < - 5 or t > - 5

f (x) = \frac{- 2 x - 9}{4 x - 19}

f (x) = 2 e^{- x} - 3

8 x - 4 y = 20

f (x) = t^{\frac{1}{3}}

y = 4 x - 1

What is the domain of-(21)/((5+t)^2) ?
The domain of-(21)/((5+t)^2) is t<-5\lor t>-5
