domain of f(x)= 1/((x+2)(x-4))

domain

f (x) = \frac{1}{( x + 2 ) ( x - 4 )}

x < - 2 or - 2 < x < 4 or x > 4

Interval Notation

(- \infty, - 2) \cup (- 2, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2, x = 4

The function domain

x < - 2 or - 2 < x < 4 or x > 4

What is the domain of f(x)= 1/((x+2)(x-4)) ?
The domain of f(x)= 1/((x+2)(x-4)) is x<-2\lor-2<x<4\lor x>4
