domain of 2/(x+1)+(x/(x+1))

domain

\frac{2}{x + 1} + (\frac{x}{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

(16 - x)^{4}

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

f (x) = \frac{4 - x ^{2}}{x ( x ^{2} - 9 )}

f (x) = 2 x + 4 - 3

f (x) = 3 5 x^{3} + 40

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