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

domain

y = f (x) = \frac{2 x - 1}{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) = 28 - 4 x

f (x) = - e^{x} - 2

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

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

f (x) = 2 sin (x) + 1

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