Utah, the land of milk and honey where math students have courage and freedom rings true, is one of the fastest growing states in America. The state population was 2.942 million people in the year 2014, and 3.167 million people in the year 2018. For the prompts below, you may approximate this as an exponential function with a constant growth rate. What is the annual percentage growth rate between 2014 and 2018, rounded to two decimals?
