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

domain

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

1 \leq x < 3 or x > 3

Interval Notation

[1, 3) \cup (3, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 1

Find undefined (singularity) points:

x = 3

Combine real regions and undefined points for final function domain

1 \leq x < 3 or x > 3

sec (\frac{2 π}{7} x) - 2

f (x) = \frac{81}{x ^{2}}

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

2 x^{2} - 8

(- 6.4) (- 9.12)

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