domain of f(x)=(2x)/(x-1)

domain

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

x < 1 or x > 1

Interval Notation

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

Solution steps

Find undefined (singularity) points:

x = 1

The function domain

x < 1 or x > 1

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

2 y + x - 6 = 0

f (x) = - 3 x - 1

- \frac{1}{2} x + 6

2^{x + 1}

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