{(1,5),(2,15),(3,30),(4,50),(5,65), (6,70)} They notice that the acceleration is not a constant value. They decide that a fourth-degree polynomial will be the best to describe the speed of the car as a function of time. The task here is to determine the fourth-degree polynomial that fits this data set the best. Exercises Use a general fourth-degree polynomial and the data to construct six equations. Note that the equations are linear in the coefficients. Write the equations here:
