ating with the cubic spline, we approximate the underlying data with a function thuat i When interptear polynomial that passes through the data points (b) global polynomial b) a globbic and able to maintain continuity of the first and second derivatives at the dats points Ccil cubic polynomial that passes through all the data points on Lagrange interpolating formala to pass the function through all the data. (e) none of the above. 9. Given the following two coupled non-linear equations we seek by the Newton-Raphson method, and the current estimate ofthe root as??-(1,2), the element whose root of the Jacobian Ja) is: (a) -7 (b) 6 (c) 1 (d) o (c) none of the above. 10. For the given data: 45 The linear Lagrange interpolator L,j(z) is (a) 0.4z +1.4 (b) 0.4z-0.4 (c) (z +45)(47 (d) (x 14.3)/(3.5-1)(3.5-4.3) (e) none of the above
