一道简单的英语翻译数学应用题
Consider the simple function y=f(x)=1/x and construct the following set of data exact to 8 decimal places:(3.1,0.32258065)、(3.5,0.28571429)、(3.9,0.25641026),
(a) Fit the second-degree polynomial p2(x)=a+bx+cx^2 to the three data points.
(b) Determine the quadratic Lagrange polynomial p2(x) that pass through the three data points and reduce your result as the form of p2(x)=a+bx+cx^2.
再问： 有些复杂，简单一点的就行
