can someone help me answer questions 2, a, and b? With steps on how to do it please and thank you. 1. The graph below shows the concentration of a drug (in mg/L) in the bloodstream, t hours after it is takenorally. Use the graph to answer a-f.80a. What is the concentration after 8 hours?76+---------722-When t = 8 the value of y = 246864b. Over what interval(s) does the concentrationincrease? Over what interval(s) does theconcentration decrease?60-56-52-48440<= d <2 increase40362<= d <20 decrease3228fc. When is the drug at its maximum concentration?2420What is the maximum concentration of the drug?16T=2 and the maximum concentration is y = 64128-d. After the drug reaches its maximumconcentration, how many hours are required for theconcentration to decrease to 16 mg/L?9 10 11 12 13 14 15 16 17 18 19 208 hourse. What does the graph predict about theconcentration after 1 week? After 1 month?the graph predicts that the concentrationwill approach 0 after 1 week and after 1month.f. Summarize the concentration of the drug in thebloodstream for the first 20 hours after it is taken.Page 2 of 5Use findings from a-e to validate your statements.2. Suppose another drug is administered intravenously. The concentration c of the drug (in mg/L) in the20tbloodstream, t hours after it is administered, is modeled by the function c(t) =t*+4a. Determine when the concentration will be 0.5 mg/L.b. Complete the table representing the concentration of the drug in the bloodstream, t hours afteradministration. Round to two decimal places as needed.246101214161820c(t)
