Question

已知x=0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.O,1.1,1.2,1.3,1.4,1.5,1.6,1.7,1.8,1.9,2.0};

Y={5.8955,3.5639,2.5173,1.9799,1.8990,1.3938,1.1359,1.0096,1.0343,0.8435,O.6856,0.6100,0.5392,0.3946,0.3903,0.5474,0.3159,0.1370,0.2211,0.1704,0.2636} .
根据拟合的方法，给出y与x的函数关系，并对误差进行分析

Answer 1

用EVIEW软件 就OK了
把数据输进去 按提示来就行了

Answer 2

y=f(x)

Answer 3

y=f(x) ，只要慢慢算就OK了！
