domain of f(x)= 2/(x-3)

domain

f (x) = \frac{2}{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

2 + x

f (x) = 5 (\frac{x}{4}) - 3

7 x + 5

f (x) = \frac{x + 2}{x + 4}

- 3 sin ((π (x)) + 2)

What is the domain of f(x)= 2/(x-3) ?
The domain of f(x)= 2/(x-3) is x<3\lor x>3
