Which of the following statements is correct for the function A(I)=- 1/2x^2 +9x, where A(l) is the area of a rectangle of length l in square meters? a. The area has a minimum value of 40 1/2 square meters. 2. The area equals 18 square meters when the length is 0 meters. C. The area equals 40 1/2 square meters when the length is 9 meters. d. The area has a maximum value of 9 square meters.​

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.
