The side length of a square is increasing at a rate of 15 millimeters per second. At a certain instant, the side length is 22 millimeters. What is the rate of change of the area of the square at that instant (in square millimeters per second)?

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.
