Every moming a patient recelves by injection the same dose of a drug just after a biood test to measure the concentration of the crug in the blood. The drug concentration in the blood increases by 4 units after each injection. Over a period of 24 hours between the blood fests. 70% or the drug in the blood is removed by the system. a) Write the inear DTDS for the drug concentration. Answer xt+1=f(xt), where the updating function is f(x)= b) Find x4 when x0=0.2. Give your answer witt an accuracy of at least two decimal places. Answer x4= c) Find the fixed point of this DTDS. Give an exact answer Answer d) Draw ithe updating function and start the cobwebbing process at x0=0.2 Do at least these ilentions Remember to alwas start your cobweb on the honzontal axis. Click on the leff button of your mouse to enter a comer point of your cobweb You can alway defust the coordinates or the last point that you have entered using the field with the coordinates and pressing the relum key.
