domain of f(x)=(1-3t)/(5+t)

domain

f (x) = \frac{1 - 3 t}{5 + t}

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

y = 64 - x^{3}

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

f (x) = x^{4} - 8 x^{2}

(x - 1)^{2} + 1

f (x) = \frac{3}{9 - x ^{2}}

What is the domain of f(x)=(1-3t)/(5+t) ?
The domain of f(x)=(1-3t)/(5+t) is t<-5\lor t>-5
