Determine if a linear function or exponential function will be a better model for the population of NYC from 1950 to 2020

X=city
1950
1960
1970
1980
1990
2000
2010
2020

Y= NYC (millions)
12.34
14.16
16.19
15.60
16.09
17.81
18.37
18.80

Question 1- show your work showing the coefficient of correlation (r) of both linear and exponential to prove you claim and explain how you know
Question 2- using the model or equation,what is the predicted population of NYC IN 2030? (Round off answers to 3 decimals places or thousands place)
