domain of f(x)=(3x+1)/(x+8)

domain

f (x) = \frac{3 x + 1}{x + 8}

x < - 8 or x > - 8

Interval Notation

(- \infty, - 8) \cup (- 8, \infty)

Solution steps

Find undefined (singularity) points:

x = - 8

The function domain

x < - 8 or x > - 8

f (x) = lo g_{10} (x^{2} - 2 x - 15)

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

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

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

sin (x - 4)

What is the domain of f(x)=(3x+1)/(x+8) ?
The domain of f(x)=(3x+1)/(x+8) is x<-8\lor x>-8
