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

domain

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

mi d p o in t (- 2, - 7), (0, 5)

a sy m pt o t es \frac{x ^{3} - 3 x ^{2} - 4 x}{x - 4}

d o main f (x) = \frac{1 - 3 x}{2}

a sy m pt o t es - (\frac{1}{3})^{x}

d o main f (x) = \frac{2 x ^{3}}{2 x + 2}

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