Triangle STU with vertices S(-1, -6), T(0, -3), and U(3, -4) in the line y = -x.

I don’t really know but I think

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.

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
