Part E: Linearity and Time Invariance

A.) The system is time variant. The coefficient in front of the delta symbol is directly related to the value of n.

B.) Given the example of how the system reacts to the delta function when n=0, one can assume it would react similarily with the unit step function. Therefore : $ X[n] = u[n] $
