domain of f(x)=(x+2)/(-x-1)

domain

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

x < - 1 or x > - 1

Interval Notation

(- \infty, - 1) \cup (- 1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1

The function domain

x < - 1 or x > - 1

f (x) = 0 - 1

f (x) = \frac{3}{( x - 8 ^{2} + 14 x )}

f (x) = 9 x^{3} + 3 x^{2} = 3 x

y = \frac{2 - 2 x}{x - 2}

3 x^{2} - 5 x - 6

What is the domain of f(x)=(x+2)/(-x-1) ?
The domain of f(x)=(x+2)/(-x-1) is x<-1\lor x>-1
