Answer:
The correct option is 1.
Step-by-step explanation:
The given function is
[tex]f(x)=\frac{x}{4}[/tex]
It can be written as
[tex]y=\frac{x}{4}[/tex]
[tex]4y=x[/tex]
Here, x is the domain of the function and y is the range of the function.
The range of the function is {28, 30, 32, 34, 36}, so the elements of domain are
[tex]x=4(28)=112[/tex]
[tex]x=4(30)=120[/tex]
[tex]x=4(32)=128[/tex]
[tex]x=4(34)=136[/tex]
[tex]x=4(36)=144[/tex]
The domain of the function is {112, 120, 128, 136, 144}.
Therefore option 1 is correct.
