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

domain

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

2 x - 8

F (s) = \frac{5}{25 + s ^{2}}

x^{2} - 12 x + 35

m (x) = \frac{11}{3} x - 5

f (t) = 5 - 16 t

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