I'll just get right to the point and give the problem.
"If a 100 mg (milligram) tablet of an asthma drug is taken orally and if none of the drug is present in the body when the tablet is first taken, the total amount of A in the bloodstream after t minutes is modeled by the function:
a) How many minutes are needed for 70mg of the drug to enter the bloodstream? Find the answer in decimal form.
b) Draw the graph of the function for the first two hours (120 minutes). Label the axes and indicate the value of any asymptotes for your graph."
Any help, please?
100(1-e^(-0.05*24.0795)) , right?
Whenever I try to graph it, it gives me a window error because when I press ZoomFit, it places the Ymin and Ymax at the same value. But even when I change the values manually, all the graph shows me is a straight line.
