Linear Separability After First Layer

$1$ point possible $($graded$)$

For this problem, let us focus on a network with one hidden layer and two units in that layer:

Let denote the output of the two units in the hidden layer corresponding to the input respectively, i$.$e$.$

Consider the set $.$

Assume that f is the linear activation function given by $.$

For which of the following values of weights would the set be linearly separable? $($Select all that apply.$)$
