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

domain

f (x) = \frac{x ^{2} + 1}{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 = \frac{4}{\frac{2}{x - 1} + 3}

\frac{3 x + 1}{5}

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

f (x) = x - 3 + 1

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

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