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

domain

f (x) = \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

(1, - 2), (7, 6)

\frac{3}{x + 1} + 2

f (x) = \frac{x}{4 x + 9}

(5, 2), (2, 4)

f (x) = x^{2} + 2 x - 15

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