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

domain

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

x < 2 or x > 2

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 2

The function domain

x < 2 or x > 2

f (x) = x^{2} - 6 x + 7

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

f (x) = x^{4} - 16 x^{2}

4 x + 15

f (x) = \frac{4}{x ^{2} - 9}

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