If a certain place's population is given to be growing at a rate of 4.8% annually, the population after t years from 2003 will become (1.048^t) times the given initial population. This translates to a mathematical equation which is equal to,
At = (584,658(1.048^t)
Results in the most extreme 5% of possible outcomes
Hope this helps :)
The equation would be y = -2/3x + 8
