A market research firm keeps track of the amount of movie tickets sold each year. They noticed in the years 2017 and 2023, there were 1,383 million movie tickets purchased in the United States. The minimum amount of tickets purchased occurred in 2020 and totaled 1,320 million movie tickets purchased.

The years can be represented by x and the number of movie tickets purchased, in millions, can be represented by f(x). 

Enter a value of a that could be used to express the quadratic function in standard form to model the number of movie tickets purchased, in millions. 

f(x) = ___x² + bx + c
