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

domain

f (x) = \frac{3}{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

g (x) = - 2 (x - 3)^{2} + 7

f (x) = - x^{2} + 8 x

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

f (x) = 4 x^{3} - 5 x - 1

1.5 (2)^{x}

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