To figure out the right time frame for our mosquito population growth model, we need to think about how long we’re watching the mosquitoes and what’s happening in the city. Since the city is planning to spray for mosquitoes after 11 days, we should focus on the time starting from when we begin our observations up to when the spraying happens.
So, the domain for the number of mosquitoes (let’s call it n) in relation to the number of days (which we'll call t) would be:
0 ≤ t ≤ 11
This means we’re looking at all the days from day 0 (when we start watching) to day 11 (when the spraying takes place).
