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

domain

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

f (x) = \frac{x ^{2} - 4}{x ^{2} + x - 12}

sin (x - 4)

f (x) = 7 x^{2} + 1

\frac{2}{3} tan (2 x + π)

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