domain of 3/((x+2)(x-1))

domain

\frac{3}{( x + 2 ) ( x - 1 )}

x < - 2 or - 2 < x < 1 or x > 1

Interval Notation

(- \infty, - 2) \cup (- 2, 1) \cup (1, \infty)

Solution steps

Find undefined (singularity) points:

x = - 2, x = 1

The function domain

x < - 2 or - 2 < x < 1 or x > 1

g (x) = x^{2} - 8 x + 12

f (x) = x (x + 13) + 40

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

f (x) = x^{3} - 12 x + 7

What is the domain of 3/((x+2)(x-1)) ?
The domain of 3/((x+2)(x-1)) is x<-2\lor-2<x<1\lor x>1
