The population continues to grow at an increasing rate for 5 years. In 2000 the population reached 300,000 people. The population continues to increase but the rate decreases until in 2007 the number reached 350,000 people. After that, the rate continued to decline for 3 years with a population of 320,000. The rate then rises again and the population reaches 280,000 in the long run.Represent this information in graphic form. B.
