1. Population of Ireland By Mrs. Banks

2. Population of Ireland x-valueYear Population in millions (y-value) First Differences Successive Ratios 019163.14 --- 119262.97 -0.170.95 219362.97 0.001.00 319462.96 -0.011.00 419562.90 -0.060.98 519662.88 -0.020.99 619763.37 0.491.17 719863.54 0.171.05 819963.63 0.091.03 920064.24 0.611.17 Ireland’s population is exponential because the successive ratios are close to the same number. The average ratio is 1.04 which means the population is growing by 4% each year.

3. Functions Explicit Function: y=3.14*1.04^x Recursive Function: P y *1.04 = P y+1 Prediction for 2026 is 4.59 million assuming the population grows by 4% each year.

4. Model I believe my prediction is fairly accurate because it follows the general trend or direction of both my data and explicit function.

5. Note from Mrs. Banks Feel free to put each fact on its own slide and add pictures as well as a design to make your presentation more visually appealing and professional. You will be presenting this information to the class on next Monday 2/2/2015!
