The best model was the quadratic equation because the correlation coefficient was the closest to 1 and the lowest residual is the "expreg".

I predict that by year 2887, Hepatitis B virus would shrink down to 1 infection per year. However, it'll rise back again over sometime and drop back down. I used a calculator to find that prediction by using the quadratic model. I typed the equation in and asked the calculator to help me find the time of when this virus nearly disappears.
