Question

James types 25 words per minute. He spends 15 minutes typing his homework. What is the domain of this situation?
1. (all numbers between and including 0 and 15)
2. (all numbers between and including 0 and 25)
3. Call numbers between 0 and 15)
4. (all numbers between 0 and 25)

Answer 1

Answer:

1. All numbers between, including 0 and 15.

Step-by-step explanation:

The domain is the independent variable (x), so in this case, it's be the amount of time James spent typing. James types for 15 minutes, so of course 0 and 15 have to be included, as it'll give a complete graph of what he's done so far.
