Find the linear and quadratic functions that best fit the data points (0,6.8), (1,6.3), (2,5.8), (3,5.7), and (4,5.9). Which of the two functions best fits the data? . . . The linear function that best fits the data points is y = (Type an expression using x as the variable. Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.) The quadratic function that best fits the data points is y = (Type an expression using x as the variable. Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.) The function that best fits the data is the function. linear quadratic
