6. Find the intervals where the curve is concave up or concave down and the coordinates of any points of inflection for y=xe* (4) 8. Car A is traveling west at 50 km/h and car B is traveling north at 60 km/h. Both are headed for the intersection of the two roads. At what rate are the cards approaching each other when car A is 0.3 km and car B is 0.4 km from the intersection? Round your answer to the nearest tenth. (4) 6.
