domain of f(x)=(x-1)/(x-3)

domain

f (x) = \frac{x - 1}{x - 3}

x < 3 or x > 3

Interval Notation

(- \infty, 3) \cup (3, \infty)

Solution steps

Find undefined (singularity) points:

x = 3

The function domain

x < 3 or x > 3

y = - 8 x + 6

f (x) = 3 x^{2} - 4 x^{3} - x + 1

13 - x

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

f (x) = \frac{x ^{2} - 9}{x + 1}

What is the domain of f(x)=(x-1)/(x-3) ?
The domain of f(x)=(x-1)/(x-3) is x<3\lor x>3
