Answer:
Option (3). x < 3
Step-by-step explanation:
Given function is a logarithmic function,
[tex]y=\text{ln}[\frac{(-x+3)}{2}][/tex]
We know that logarithm is defined for all positive real numbers except zero.
[tex]\frac{(-x+3)}{2}>0[/tex]
(-x + 3) > 0
-x > -3
x < 3
That means the given logarithmic function is defined for all real values lees than 3.
And the domain of the function will be x < 3
Option (3) will be the answer.
