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

domain

\frac{2}{x + 1} \cdot \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) = \frac{5}{11} x + 10

x^{2} + 5 x + 6

4 x^{2} - 4 x + 21

(- 2, 3), (2, 1)

What is the domain of 2/(x+1)*x/(x+1) ?
