Output of a scalar ReLU unit · formula reference
This asks for a forward pass, not the derivative at the nondifferentiable point zero.
Formula
This asks for a forward pass, not the derivative at the nondifferentiable point zero.
ReLU(z) = max(0,z)
Worked example
A neuron computes ReLU(wx+b) with w=3, x=-6, b=-3. Find its output. Round the final result to 4 decimal places if needed.
The preactivation is -21. Keep that number if positive; otherwise return 0.

Prerequisites and checking
Algebra and the topic definitions. Keep units and rounding consistent. State the model conditions before applying the formula.
