domain of f(x)=(x-1)/(x^2+x-2)

domain

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

g (x) = - 3 (x + 6)

f (x) = \frac{2 x ^{2} - 4}{5 x ^{2} + 45}

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

y = - 4 x - 5

f (x) = ln (2 - x)

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