Abuilding across the street casts a shadow that is 24 feet long. your friend is 6 feet tall and casts a shadow that is 4 feet long. what is the hieght of the building

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.

There is no question, there is just the answer.
