Use the type of regression function specified to make a prediction from the given data.The table below shows the number of subscribers to a certain magazine in various years. Use regression to fit an exponential function N(t) = abt to the data where t is the number of years since 1980 and N is the number of subscribers in thousands. Round regression coefficients to four decimal places.
A. N(t) = 4.0399(0.1492)t B. N(t) = 1.7349(1.2109)t C. N(t) = 3.1672(1.1862)t D. N(t) = 4.0399(1.1609)t
