9–17 Consider the waveform in Figure P9–17.

(a) Write an expression for the waveform f t ð Þ using step and ramp functions.

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