domain of f(x)=(2x^2-3)/(x^2+2x+1)

domain

f (x) = \frac{2 x ^{2} - 3}{x ^{2} + 2 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) = 60 x^{2} - 20 x^{3}

- 2 x^{2} + 5 x - 6

f (x) = \frac{9}{x ^{2}}

f (x) = x^{4} + 4 x^{3} + 7

8 x

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