domain of (x+4)/(-2x-6)

domain

\frac{x + 4}{- 2 x - 6}

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

f (x) = 2 x - 6

\frac{1}{arccos ( x )}

f (x) = \frac{5 x - 10}{x ^{2} + 5 x - 14}

f (x) = \frac{1}{x ^{2}} - 3

f (x) = \frac{1}{x ^{2}} + 1

What is the domain of (x+4)/(-2x-6) ?
The domain of (x+4)/(-2x-6) is x<-3\lor x>-3
