domain of (2x+5)/(x+3)

domain

\frac{2 x + 5}{x + 3}

x < - 3 or x > - 3

Interval Notation

(- \infty, - 3) \cup (- 3, \infty)

Solution steps

Find undefined (singularity) points:

x = - 3

The function domain

x < - 3 or x > - 3

y = 2 x^{2} + 8 x - 6

f (x) = x^{3} - x

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

f (x) = - x^{3} - 2 x^{2} - 4 x - 3

\frac{2}{1 - e ^{x}}

What is the domain of (2x+5)/(x+3) ?
The domain of (2x+5)/(x+3) is x<-3\lor x>-3
