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

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

ln (x^{2} + 3 x - 4)

f (x) = 10 x^{4} - 60 x^{2}

2^{x + 3} + 4

f (x) = ln (8 x - 7)

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
