domain of f(x)=(4x^2-4)/(x+1)

domain

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

(- 6, 12), (2, - 20)

(3, 9), (0, 5)

\frac{2 x - 6}{x ^{2} - 4 x + 3}

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

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

What is the domain of f(x)=(4x^2-4)/(x+1) ?
The domain of f(x)=(4x^2-4)/(x+1) is x<-1\lor x>-1
