domain of (1-5t)/(4+t)

domain

\frac{1 - 5 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

y = 3, (- 14, 8)

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

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

\frac{x}{- x + 1}

f (x) = - \frac{3}{4} + 5

What is the domain of (1-5t)/(4+t) ?
The domain of (1-5t)/(4+t) is t<-4\lor t>-4
