domain of (1-2t)/(4+t)

domain

\frac{1 - 2 t}{4 + t}

t < - 4 or t > - 4

Interval Notation

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

Solution steps

Find undefined (singularity) points:

t = - 4

The function domain

t < - 4 or t > - 4

f (x) = - x

f (x) = \frac{10 x ^{2} + 35 x}{49 x ^{2} - 28 x + 4}

f (x) = ln (x^{2} - x - 20)

4 x - 3 y = 12

f (x) = \frac{3 x ^{2} + 6}{x ^{2} - 2 x - 3}

What is the domain of (1-2t)/(4+t) ?
The domain of (1-2t)/(4+t) is t<-4\lor t>-4
