Question

Hi, i asked an expert for a solution to this question. I would like to know why the second term is included in b? (the -e^(7-s)5)

Consider a piece-wise continuous function f such that
f(t)e
¬stdt = e(7-s)t _ e(7-s)5
for all t > 5.
(a) Determine the domain of the Laplace transform
L(f) of f.
(b) Compute the Laplace transform of f, in the case
when f(t) = 10 for all t e [0, 5].
