    find quadratic equation from a table of values.

    (1,14000), (2,9100), (3,6200), (4,4000), (5,3000). I need to find the quadratic equation what would suit those points. It says to use a graphing calculator but I don't have one and I cannot get access to one since I am doing this work independantly
