Answer 1

The domain of the function is all real numbers from 0 to 20, and the range is all real numbers greater than or equal to 0, as the function is represented on a graph as a horizontal line within the given domain. Therefore correct option is C

Step-by-step explanation:

The question asks to determine the domain and range of a function based on its graph representation. For the given function, which is represented as a horizontal line within the interval of 0 to 20 on the x-axis, the domain would include all real numbers between and including 0 and 20, not just integers.

Therefore, the domain is 0 ≤ x ≤ 20. Since it is a horizontal line, the range would be the singular y-value that the function takes within this domain, which is, in this case, a number greater than or equal to zero.

Given that there is no indication that the function goes below the x-axis, the range would be y ≥ 0.

The correct answer would then be that the domain includes all real numbers, and the range is y ≥ 0.
