Consider the waveform in Figure P9–17.

(a) Write an expression for the waveform f(t) in Figure P9–17 using step functions.

(b) Use the time-domain translation property to find the Laplace transform of the waveform f(t) found in part (a).

(c) Verify the Laplace transform found in

(b) by applying the definition of the Laplace transformation in Eq. (9–2) to the waveform f(t) found in (a).
