6- Use the Lagrange Interpolation Method to find the interpolating polynomial of the given points. In your calculations, simplify and expand all the fractions while finding Li terms. Your final answer should be in an expanded form where each power of "x" is explicitly determined: $x_i$ -2 0 1 2 $y_i$ -20 -5 2 40

Lagrange Interpolating Polynomial For the set of data points provided below: Determine the second-order polynomial in the Lagrange form that passes through the points. Note: Choose three representative points from the set of data points. Plot the second-order polynomial found in part (a) and all data points. Use the polynomial obtained in part (a) to determine the interpolated value for x= 3.5.
