Which of the following correctly describes the domain of the function shown below?

D

Step-by-step explanation:

The denominator of r(x) cannot be zero as this would make r(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be , that is

2x = 0 → x = 0 ← excluded value in domain

Then

domain is { x : x ≠ 0 }

i think its a and d
