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

domain

f (x) = (\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

f (x) = 3 x + 15

f (x) = 2 x^{2}

(8, - 9), (8, 5)

- \frac{3}{4} x - 1 + 4

\frac{x + 5}{x - 2}

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