Complete matrix A_reflection_yaxis , which corresponds to the reflection about y-axis, and find its eigenvalues and eigenvectors. Visualize the result and investigate it. How would you interpret this linear transformation in terms of the eigenvectors and thier eigenvalues?

If we use the matrix mentioned before (the A matrix)

Its reflection along the y axis is

-2, 3
-2, 1

But i keep getting failing tests saying:

Wrong matrix A_reflection_yaxis.
Check the element in the row 1, column 1

I believe it’s important to clarify that in the exercise, as it can be confusing. The request is for A_reflection_yaxis, leading me to interpret it as the reflection of the matrix A, which was previously provided, about the y-axis
