Step 1
The second-order Lagrange interpolating polynomial is given by: $$P_2(x) = \sum_{i=0}^2 y_i L_i(x)$$ where $$L_i(x) = \prod_{j=0, j \ne i}^2 \frac{x - x_j}{x_i - x_j}$$ Show more…

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.

Use Lagrange Interpolation to generate a polynomial, P3(x), of order three for the given points (1, 2), (2, 4), (3, 9), (4, 16). Do NOT simplify the polynomial to the form a1x3 + a2x2 + a3x + a4. Use P3(x) to calculate the value at x = 5.
