domain of f(x)=(x+5)/(x-3)

domain

f (x) = \frac{x + 5}{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

\frac{3}{x ^{2} - 4}

f (x) = (x + 3)^{5}

(4, - 5), (8, 7)

f (x) = \frac{7 x - 1}{5 x + 6}

(- 7, 2), (8, 10)

What is the domain of f(x)=(x+5)/(x-3) ?
The domain of f(x)=(x+5)/(x-3) is x<3\lor x>3
