For questions 1 - 4, use your graphing calculator to help you sketch a graph of the function given. Then state whether each function is one-to-one. In each case, explain how you know.

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.

The answer would be 484

The answer would be d
