I would like to determine and plot a LTI system's output [ y(t) ] .
I know that y(t) can be determined by convolving input and impulse response, or y(t) = x(t) * h(t), but I can't figure out how to plot output correctly.

x(t) does not include that term ε(t) . So as written x(t) is non-zero for t < 0. Is that the correct interpretation of x(t)?

Do you mean:
  1. create a list of t
  2. compute y for the list of t above
  3. plot(t, y)

Well one way to verify is to pick several points of t, compute x(t), h(t) and y(t) by hand (or say use a calculator). Then verify y(t) on the figure is correct.
