4. Consider the following set of points: (3,4), (1,2), (-1, 1), (6,5), (7,9). Find a polynomial of degree two y best fits the points given above Enter this points in a matrix: Type: E4- 3 1-16 7;4 2 1 5 9;1 11 1 a1z + ao, that To create a matrix of x-values Type: To create a matrix of y-values Type: Y = E4(, 2) Create a 5 x 3 matrix A4 Type: The first column is the x -values raised to second power. The second column is x-values. The Third column is ones Now in A4 c = b the vector x is a2 ao and b is the vector of y-values. Type: Then find the solution to the normal system A4tA4X - 44%. To solve this system you may find rref([A41A4 A4 Type: Enter Your Answers for a2, a1 and ao as Type: a2 = Your answer for a2 Type: al Your answer for al Type: a0 Your answer for ao
