domain of f(x)= 4/(x+8)

domain

f (x) = \frac{4}{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

y = 4 x

f (x) = \frac{x - 3}{x - 4}

y = \frac{x ^{2}}{1 + x ^{2}}

f (x) = \frac{x}{x ^{2} + 7}, - 6 \leq x \leq 0

f (x) = x - 1 - x^{2}

What is the domain of f(x)= 4/(x+8) ?
The domain of f(x)= 4/(x+8) is x<-8\lor x>-8
