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

domain

y = \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

y = - 2 x + 125 {3, 9 \leq y \leq 50}

y = x^{2} - x - ln (x)

f (x) = \frac{( x + 1 ) ^{3}}{( x - 1 ) ^{2}}

f (x) = x^{2} - 4 x + 6

y = \frac{1}{3 x ^{2} - 33 x + 54}

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