How are using graphs, equations, and tables similar when distinguishing between proportional and nonproportional linear relationships

They are similar because they all give you the same answer and they show whether or not they go through the integer.

Polar coordinates is 8,9

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.
