Q$50.$ Given the single perceptron shown below with the ReLu activation function, perform the following: $1.$ In the shaded squares above the line, perform a forward pass calculation and show the outputs of the forward pass. Fill all shaded squares.

$2.$ Using the backpropagation algorithm, indicate the values shown in the spikey circles.

$3.$ To decrease the value of the output, indicate whether the values of the following variables should be increased or decreased?

Hint: The ReLu function is defined as $f(z)=\{\begin{array}{cc}0,& z<mn\; id="EditorElement\_244106">0</mn>\\ z,& z0\end{array}$
