Answer 1

The context is best represented by the equation \( t(n) = 900 - 10n \), where \( t(n) \) is Mya's time in seconds for the nth race, starting with her first race at \( n = 0 \) (15 minutes = 900 seconds).

The domain is \( n \geq 0 \), where \( n \) is a non-negative integer representing the number of races Mya has competed in.
