Suppose in the traffic flow model the speed v of cars is taken to be a positive monotonic differentiable function of density: v = v (u).
Can there be two local maxima of the flux? (Hint: Make Q (u) quartic.)

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.

+1,000)=g7e=mc2-g=7 because if you know algebra you should know g=7 to get your answer
