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

domain

\frac{x ^{2} - x - 2}{x - 1}

x < 1 or x > 1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 1

The function domain

x < 1 or x > 1

1 - 2 x - 3

f (x) = 9 - x^{2}

f (x) = 3 x^{4} + 8 x^{3} + 4

f (x) = \frac{5}{( x - 4 ) ^{3}}

f (x) = x^{2} - 9 x

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