''For the period of 200 days last year, you have charted fluctuation in prices of stock market. On following days, net change in stock market was zero:25th, 39th, 65th, 83rd, 102nd, 127th, 157th, and 170th. You feel that if you make net change at day zero equal to 89,774.001, then you will more closely approximate real situation with the POLYNOMIAL model for period from 25th thru the 170th day."
Write the function which represents the polynomial model of stock market, plotting net change in total stock market and the day.
