Use the type of regression function specified to make a prediction from the given data.The table below shows the population of a city in the years 1990 through 1994. Use regression to fit an exponential function P(t) = P0ekt to the data where t is the number of years since 1990 and P is the population in millions. Round regression coefficients to four decimal places.
A. P(t) = 0.6494 e0.2557t B. P(t) = 0.2494 e0.3728t C. P(t) = 6.1981 e0.0457t D. P(t) = 1.2861 e0.2209t
