Question

Determine the domain of the function?

1) (–1, 5) (5, 5) (–[infinity], –1) u (–1, 5) u (5, [infinity]) (–[infinity], –5) u (–5, 5) u (5, [infinity])
2) (–1, 5) (5, 5) (–[infinity], –1) u (–1, 5) u (5, [infinity])
3) (–[infinity], –5) u (–5, 5) u (5, [infinity])
4) (–1, 5) (5, 5) (–[infinity], –1) u (–1, 5) u (5, [infinity]) (–[infinity], –5) u (–5, 5)

Answer 1

The domain of the described function is all real numbers between and including 0 and 20.

Step-by-step explanation:

To determine the domain of the function described, we consider that the function is defined for all real numbers between 0 and 20, inclusive. A horizontal line in a graph typically means that the function has the same output for every input within its domain. Hence, every x-value from 0 to 20 is included in the domain of the function. Considering the restrictions given (0 ≤ x ≤ 20), the domain is all real numbers between and including the endpoints 0 and 20.
