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

domain

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

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 = 1, x = - 2

The function domain

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

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

(- 7, 3), (6, - 4)

y = 2^{x}

s + 1

f (x) = (x - 4)^{2}, x \geq 4

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