domain of f(x)=(2x^3)/(2x+2)

domain

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

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

y = 3 x - 8

f (x) = 7 x^{2} + 6

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

x^{4} - x^{2}

What is the domain of f(x)=(2x^3)/(2x+2) ?
The domain of f(x)=(2x^3)/(2x+2) is x<-1\lor x>-1
