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

domain

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

x < - 1 or - 1 < x < 4 or x > 4

Interval Notation

(- \infty, - 1) \cup (- 1, 4) \cup (4, \infty)

Solution steps

Find undefined (singularity) points:

x = - 1, x = 4

The function domain

x < - 1 or - 1 < x < 4 or x > 4

f (x) = - e^{x + 1}

\frac{x - 1}{x + 1}

f (x) = 2 + x - x^{2}

f (x) = 7 x + 14

f (x) = \frac{x}{2 x - 8}

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