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

domain

f (x) = \frac{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

y = cot (θ)

f (x) = \frac{x}{4} - \frac{1}{x - 3}

f (x) = 10 - 3 x - x^{2}

- lo g_{4} (x)

f (x) = 2 x - 1 + 3

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