domain of f(x)=(6x)/(x+3)

domain

f (x) = \frac{6 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

m o n o t o n e f (x) = (x - 1)^{2} - 4

in t erce pt s f (x) = - 4 x^{2} - 6 x + 2

cr i t i c a l f (x) = x

d o main f (x) = t - 9

a sy m pt o t es f (x) = \frac{x ^{2} + 3}{x ^{4} + 4 x ^{2} - 5}

What is the domain of f(x)=(6x)/(x+3) ?
The domain of f(x)=(6x)/(x+3) is x<-3\lor x>-3
