domain of f(x)=(x^2-4)/(x^2-2x)

domain

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

x < 0 or 0 < x < 2 or x > 2

Interval Notation

(- \infty, 0) \cup (0, 2) \cup (2, \infty)

Solution steps

Find undefined (singularity) points:

x = 2, x = 0

The function domain

x < 0 or 0 < x < 2 or x > 2

(\frac{1}{2})^{x} - 1

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

f (x) = - 4 ∣ x ∣

f (x) = \frac{x + 5}{x ^{2} + 10 x + 25}

What is the domain of f(x)=(x^2-4)/(x^2-2x) ?
The domain of f(x)=(x^2-4)/(x^2-2x) is x<0\lor 0<x<2\lor x>2
