While on vacation, fred reads a marker stating that the town he is visiting has an elevation of 350 feet above sea level. what is the correct way of stating this elevation as a rational number?

I think 350 is how you state it as a rational number since its above the sea level, im not completely sure though (:

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.
