domain of (x^2-3x+2)/(x^2-4)

domain

\frac{x ^{2} - 3 x + 2}{x ^{2} - 4}

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

Solution steps

Find undefined (singularity) points:

x = 2, x = - 2

The function domain

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

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

f (x) = \frac{2 x ^{2} - 6 x}{x ^{2} - 2 x - 3}

f (x) = 2 x + 2

f (x) = \frac{2 x ^{2} - 6 x + 4}{- 3 x + 5}

x^{2} + 10
