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

domain

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

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

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 2, x = - 4

The function domain

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

f (x) = 0.5 x^{3}

csc (x)

4 sin (3 x - π)

f (x) = \frac{1}{arccos ( x )}

f (x) = \frac{x - 5}{x + 4}

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