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

domain

h (x) = \frac{2 x}{1 + x}

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

2 sin (x) + sin (2 x)

\frac{x ^{2} + 7 x + 12}{- 2 x ^{2} - 2 x + 12}

f (x) = lo g_{6} (4 x + 4)

- 8 x^{2} + 4

f (x) = - 2 x^{2} + 4 x - 7

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