domain of f(x)=(x^2-2x)/(x^2-3x+2)

domain

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

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

Interval Notation

(- \infty, 1) \cup (1, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = 1

The function domain

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

f (x) = \frac{5 x + 14}{6 x ^{2} + x - 2}

f (x) = \frac{x + 9}{x ^{2} - 49}

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

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

f (x) = \frac{22}{4 x - 15}

What is the domain of f(x)=(x^2-2x)/(x^2-3x+2) ?
The domain of f(x)=(x^2-2x)/(x^2-3x+2) is x<1\lor 1<x<2\lor x>2
