Please provide your solution for parts B and C in the form of a MATLAB code. Ignore part A.

You are given the following errorless data set: x 1 2 3 5 7 00 f(x) 3 6 19 99 291 444 a. Use nearest neighbour interpolation to find f(x) for the following x values: 2.8, 4.4, and 7.1 b. Implement a MATLAB function or script to perform interpolation based on the closest 2, 3, and 4 points using Lagrangian interpolating polynomials C. Run your function/script on the x values given in a) for the closest 2-, 3-, and 4-point Lagrangian interpolating polynomial
