In 1990, Nigeria had a population of about 95.3 million. By 2000, there were about 122.4 million people, an increate of about 28.4%. During that decade, the populatio can be reasonably modeled by an exponential function. Express the population of Nigeria f(d), in millions of people, d decades since 1990.
