1. 0.7654, 0.1, 0.09, 0.08 how you do this is that you look for all the numbers that are right after the decimal mark, and compare all the numbers that are similar, to see which one is bigger. Then you continue down the line to two marks after the decimal, and see which number is bigger.

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.
