The function f(t) = -t(t - 21)(t + 1) can be used to model the measles pathogenesis curve in the figures below. The peak infection time for this function was found to be t, = 14. Use seven subintervals and their midpoints to estimate the total amount of infection needed to develop symptoms of measles. (infected cells/mL) · days N 1500 1000 500 - 10–11 14 17-18 21 (days) Infectiousness Infectiousness Pathogen enters plasma Symptoms аppear Pathogen is cleared begins ends Measles pathogenesis curve Number of infected cells per mL of blood plasma
