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

domain

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

f (x) = 10 + 3 x^{2}

f (x) = \frac{2}{9 x + 4}

f (x) = (x + 5)^{2} + 4

f (x) = \frac{2 x ^{2} + 3 x - 5}{x ^{2} + 2}

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