To determine the values in the last line of matrix A, we need to understand the structure of matrix A in the context of a quadratic model. For a quadratic model, matrix A is typically structured as follows:

A = [[1, x1, x1^2],
[1, x2, x2^2],
[1, x3, x3^2]]

Where x1, x2, and x3 are the x-values of the given points.

Given the points (2, 3), (4, 5) and (6, 7), the x-values are 2, 4, and 6 respectively.

Therefore, the last line of matrix A, corresponding to the point (6, 7), will be:

[1, 6, 6^2] = [1, 6, 36]
