domain of (2x^2-8)/(x^2+x-2)

domain

\frac{2 x ^{2} - 8}{x ^{2} + x - 2}

x < - 2 or - 2 < x < 1 or x > 1

Solution steps

Find undefined (singularity) points:

x = 1, x = - 2

The function domain

x < - 2 or - 2 < x < 1 or x > 1

\frac{x ^{2} + 30 x - 99}{x - 3}

f (x) = e

f (x) = lo g_{3} (lo g_{2} (x))

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

f (x) = ln (4 x - 5)

What is the domain of (2x^2-8)/(x^2+x-2) ?
The domain of (2x^2-8)/(x^2+x-2) is x<-2\lor-2<x<1\lor x>1
