Using it's concept, it is found that an appropriate domain for this situation is:
- [tex]0 \leq t \leq 10[/tex], where t represents the set of rational numbers.
- The domain of a function is the set that contains all possible input values.
In this problem:
- The input is the time in seconds, and the output is her depth, in feet.
- The time assumes rational values between 0 and 10, hence, the domain is [tex]0 \leq t \leq 10[/tex], and the correct option is:
[tex]0 \leq t \leq 10[/tex], where t represents the set of rational numbers.
