Question

Find the domain od the given function.

f(x)=
`(x)/(x-3)`

a.) all real numbers
b.) (-∞,3)∪(3,∞)
c.) (0,∞)
d.) (-∞,-3)∪(-3,∞)

Answer 1

B

Explanation:

There is a vertical asymptote at x=3. It is not defined and therefore not included in the domain.

All other numbers are included in the domain.
