Final answer:

The domain of the function, which is a horizontal line from 0 to 20 inclusive, is [0, 20].

Step-by-step explanation:

To find the domain of the function described, which is a horizontal line existing for 0 ≤ x ≤ 20, we need to identify the set of all possible 'x' values that the function can take. Since the function is defined from 0 to 20, both numbers included, the domain of the function is [0, 20]. This interval includes all the real numbers starting from 0 up to and including 20.
