domain of (2x+3)/(x+2)

domain

\frac{2 x + 3}{x + 2}

x < - 2 or x > - 2

Interval Notation

(- \infty, - 2) \cup (- 2, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2

The function domain

x < - 2 or x > - 2

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

f (x) = \frac{5 x ^{3} - x ^{2} + 4}{3 x ^{3} + 24}

6 - 3 x

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

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