Answer 1

Answer:The domain of the function is only whole numbers that are multiples of 30, when m <180

Step-by-step explanation:

It's stated above that the time duration of the lesson can be increased for upto 3 hours, which is 180 minutes (as 1 hour = 60 minutes)

And,

Half an hour is 30 minutes, it's stated that it can be increased for half am hour, which is 30 minutes

It's clear that the next numbers after 30 will also be multiples of 30 and are whole numbers as whole numbers start from 0.

Hope this helps!
