Dear DeepLearning.AI

I wonder that how the vector y can be Non-sigular Linear transformation.

First of all, I know that Vector W is Non-sigular because I can calculate the determinant of the vector W. However, I don’t understand that the vector y is Non-sigunlar matrix.

Hi @rlaskan95.

The 2nd question is referring to W which is the linear transformation. It is not referring to whether y is singular or not. The choices just put them side-by-side, but those are answers to 2 questions:

- What is y?
- Is W linear transformation singular or not?
