Answer:
D: -2 ≤ x ≤ 12
Explanation:
Hello!
The Domain of a function or graph is the set of all x values, wether in the form of an inequality or individual points, that the graph goes through.
This graph is a line that goes through all x values ranging from -2 to 12.
Since domain corresponds to x, we use the variable x as an inequality.
The domain is all values greater than or equal to -2, and less than or equal to 12.
The inequality for the domain is -2 ≤ x ≤ 12.
