Q1 - I don't get the answer
 
Why is the "+1" in the answer? I thought it would be only d since there are d dimensions in the data.

The bias b is part of the QP problem, although it is not part of the objective {1 \over 2} {\bf w}^{\rm T}{\bf w}. This is because b is part of the constraints, and its value affects the values of the {\bf w} variables in the constraints, hence it affects the objective through these variables.
