Answer:

The fourth listed answer:

Domain: All Real numbers

Range : { f{x) | f(x) [tex]\leq[/tex] 0, f(x) = 1 }

Step-by-step explanation:

The domain consists of all Real numbers (notice that you have a well defined f(x) value for all possible x on the horizontal axis.

The Range is associated with the set of those f(x) values (on the vertical axis) that are connected via the functional relationship with a value  "x" of the domain. The line with positive slope extends to all f(x) values that are [tex]\leq[/tex] 0 (smaller than or equal to zero). While the flat horizontal line on the right of the plot corresponds to the line f(x) =1 (only one value of f(x) [1} connects with the x-values of the Domain that are larger than 3.
