Hey, since there are multiple sub-parts posted, we will answer the first 3 sub-parts. If you want any specific sub-part to be answered, then please submit the question with that sub-part number in your message.1. Consider the given graph. Let y denotes the concentration of the drug in mg/L in the bloodstream after t hours it is taken orally. a. To get the concentration after 8 hours, identify the y coordinate on the graph with t = 8. When t = 8, the graph passes through the point 8,24 and thus have the y coordinate 24. So, the concentration of the drug after 8 hours is 24 mg/L. b. From the given graph, we can observe that the graph representing the concentration of the drug moves upward as t moves from 0 to 2 and the curve moves downward as t moves from 2 to infinity. This implies that the concentration of the drug increases as t moves from 0 to 2 and it decreases as t moves from 2 to infinity. Hence, the interval on which the concentration increases is 0,2 and the interval on which the concentration decreases is 2,∞.c. Since the concentration increases to the left of t = 2 and decreases to the right of t = 2, the concentration is maximum when t = 2. So, the drug is at its maximum concentration after 2 hours it is taken orally. The maximum concentration is the concentration after 2 hours. To get the concentration after 2 hours, identify the y coordinate on the graph with t = 2. When t = 2, the graph passes through the point 2,64 and thus have the y coordinate 64. So, the maximum concentration 64 mg/L.
