Answer:

The correct option is 2. The range of the function is {-6,-18}.

Step-by-step explanation:

The given function is

[tex]f(x)=3x-12[/tex]

Domain is the set of all possible inputs and range is the set of all possible outputs.

It is given that the domain of the function is {-2,2}.

For x=-2.

[tex]f(-2)=3(-2)-12=-6-12=-18[/tex]

For x=2.

[tex]f(2)=3(2)-12=6-12=-6[/tex]

Therefore the range of the function is {-6,-18} and option 2 is correct.
