Construct three parallel lines. then construct two arbitrary nonparallel transversals of the parallel lines. make sure that the transversals cut the three parallel lines at distinct points. mark the points of intersection where the transversals cut the parallel lines.

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.
