The following data is given Write a C-code to: Obtain the polynomial relation in Lagrange form that passes through the points, then use it to calculate the interpolated value of y at x=3.5. Obtain the polynomial relation in Gregory Newton s form that passes through the points, then use it to calculate the interpolated value of y at x=3.5. the following data is given: Write a C-code: Use liner regression to determine the coefficients in and b in the function y = mx + b that best fits the data
