What type of function is shown in the figure?

FInd an expression for a cubic function g if g(1) = 6 and g(-1) = g(0) = g(2) = 0

Recent studies indicate that the average surface temperature of the earth has been rising steadily and is modeled by the function  $$T=0.02t+28.50$$  where T is temperature in $$\degree C$$  and t represents number of years.  Predict the average surface temperature of the earth from year 1922 to 2022.

Find f(-1)
