To find the area of the side length of 4 units you can square the number 4 the expression (4+3) to the power of 2 gives the area of the square if the side lengths are increased by 3 units how much greater is the new square than the old one?

The area of the new square is 7^2 = 49.

The area of the old square is 4^2 = 16.

Hence, the new square is 33 greater than the old one.

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.
