The following sketch represents the distance d​ (in miles) that Kevin was from home as a function of time t​ (in hours). Answer the questions based on the graph shown to the right. In parts ​(a) to ​(g)​, how many hours elapsed and how far was Kevin from home during this​ time? Complete parts ​(a) through ​(i). A coordinate system has a horizontal t-axis and a vertical d(t)-axis that intersect at (0, 0). The following plotted points are connected by line segments from left to right: (0, 0); (3, 9); (3.3, 9); (3.9, 0). A curve rises from left to right from a plotted point at (4.2, 0) to a plotted point at (4.8, 8.5). The curve then travels horizontally to a plotted point at (5, 8.5) where it then falls from left to right at a decreasing rate to a plotted point at (6.2, 0).
