What is 60488 rounded to the nearest tenth nearest ten thousand

It is 60,000 since its rounded to the nearest ten thousand.
if it were 60,500 it would round up to 70,000 but since the number is lower than 500, the answer is 60,000

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.
