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

domain

f (x) = \frac{x + 8}{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 = x^{2} (x^{2} - 5)

f (x) = - (2 x - 3)^{2} + 5

f (x) = - x^{2} + 11 x

\frac{x ^{2} + 3 x + 5}{x ^{2} - 4 x + 3}

f (x) = \frac{x - 6}{x ^{2} + 1}

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