Philip is assigned to read a book for his literature class that is 250 pages long. he read at a rate of 30 pages per hour. if he can only read for 2 hours per day, how many days will it take him ro finish the book

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
