1. [-/0.83 Points] DETAILS TANAPMATH7 9.3.004. MY NOTES ASK YOUR TEACHER Productivity and yield of cultivated crops are often reduced by insect pests. The following graph shows the relationship between the yield of a certain crop, f(x), as a function of the density of aphids x. (Aphids are small insects that suck plant juices.) 1000- 300 Crop yield (kg/4000 m-) 1500 500- 300 150 200 400 600 800 1000 1200 1400 1600 Aphids per beam stem Here, f(x) is measured in kilograms per 4,000 square meters, and x is measured in hundreds of aphids per bean stem. By computing the slopes of the respective tangent lines, find the rate of change of the crop yield with respect to the density of aphids when that density is 200 aphids per bean stem and when it is 800 aphids per bean stem. 200 aphids per bean stem kg per 4,000 m2 per aphid per bean stem 800 aphids per bean stem kg per 4,000 m2 per aphid per bean stem Need Help?
