The product of what number and 7 is less than 49

Any number less than seven (the product is what you get when you multiply two numbers together.) Since 7*7=49, 7*anything less than 7 is less than 49.

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.
