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

domain

\frac{2 ( x - 2 )}{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

7 x + 3

7 x + 9

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

\frac{3 x + 7}{x ^{2} + 5 x + 4}

y = e^{x} - 2

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