- I research up about population in Japan.

- y - axis is population x - axis is number of every 5 year.

- I decided 2 points that (0 , 883) and (15 , 1037).

- I decided 2 points that (25 , 1158) and (45 , 1257).

- I decided 2 points that (50 , 1269) and (70 , 1223).

- I decided 2 points that (10 , 973 ) and (60 , 1265 ).

- I Made a predictions using green line what the values will be in

- I Made a predictions using QUADRATIC line what the values will be in.

- Formula of the QUADRATIC line 2067 and 2112
- Green line is up but QUADRATIC line is curve . And green line is population up but QUADRATIC line is in the last person down . In addition , from the QUADRATIC line we can also see that there may no more Japanese people 171 years later from 1945.
