population of city has varied considederably in recent years. the data it the relates the pollution P to time t, in years, where t=0 correponds to 1990. use a quadratic function fitted to the data to predict the population in 2000
data:
year,t population P
1990(t=1) 59,000
1991 t =2 48,000
1992 t=3 43,500
1993 t=4 49,000
1994 t=5 41,500
1995t=6 39,000
1996t=7 42,500

Use your favorite quadratic regression calculator. I got
P = 672.619t^2 - 7863.0952t + 64071.4286
but it's not a very good fit.
P = 672.619t^2 - 7863.0952t + 64071.4286
but it's not a very good fit.
