The following graph shows the pathogenesis curve for a certain infectious disease from the time when the pathogen enters the person's blood plasma until the pathogen is cleared from the blood plasma. 1000 500 The curve can be modeled by the function f(t) = -? + 17.6 +7.2t where t is time in days, and f(t) is the number of infected cells per mL of blood plasma. 1. Find the number of infected cells per mL of blood plasma 5 days after the pathogen enters the blood plasma. 2. Find the “peak" day, when the number of infected cells per mL of blood plasma is the greatest. How many days does that happen after infection? What is the number of infected cells per mL of blood plasma at that time? Don't just use the graph. Show your work.
