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

domain

f (x) = \frac{5 x}{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 (y) = 2 x + 5

(5.7) (- 3.1)

\frac{x - 4}{3 x + 7}

3 y = 9 - 6 x

y = (x^{2} - 4 x)^{2}

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