Please help with parts b and c

The growth of a certain species (in millions) since 1970 closely fits the following exponential function where t is the number of years since 1970. A(t) = 3300 0.0166t a. The population of the species was about 3906 million in 1980. How closely does the function approximate this value? b. Use the function to approximate the population of the species in 2000. (The actual population in 2000 was about 5540 million) c. Estimate the population of the species in the year 2015. a. Choose the correct answer below. A. The population of the species in 1980 is approximately 3396 million. This is not a close appoximation to the actual value of 3906 million, because the approximation does not take into account a massive growth increase between 1970 and 1980. B. The population of the species in 1980 is approximately 3896 million. This is fairly close to the actual value of 3906 million, because the percentage difference is very small. O C. The population of the species in 1980 is approximately 3896 million. This is not a close appoximation to the actual value of 3906 million, because the difference in the two populations is ten million, which is large. b. The approximate population in 2000 is 5,429 million. (Round to the nearest whole number as needed.)
