Using the Heaviside function u(t) write down a function y(t) that represents the plot below. You may use the plot button below to compare how your function (in green) looks compared to the given function (in red). Note: enter only the right hand side of the equation (i.e. do not enter y(t)=...). 4- 3- y 2- 1 0 2 3 4 5 t 4*u(t-1)-(t-2)*u(t-2)+3*u(1-3)-3*u(t-4)
