with the names of the variables and of the parameters are indicated

in the figure. The activation function of the hidden layer is ReLU, while the

output layer is activated by a sigmoid. All weights are zero, except for $b_2=-1,$

$w_2=2$ and $w_3=1.$ Compute the value in the output node when $($a$)x=0$;

and $($b$)x=1.$
