On April 1, 2003, there were 1,804 cases. Find an exponential model that predicts the number of cases t days after April 1, 2003. F(+) = 18040-041 X Use it to estimate the number of cases on April 24, 2003. (Round your answer to the nearest integer. The actual reported number of cases was 4,439.) cases Need Help? Read It 6.
