1. The problem statement, all variables and given/known data Find the Laplace transform of f(t). f(t) = -9t + 7 + u5(-7 + 9t + et) 2. Relevant equations 3. The attempt at a solution The Laplace transform of -9t is just -9/t2 The Laplace transform of 7 is 7/s But I am not sure how to find it for u5(-7 + 9t + et). In the tables it says ua(t)f(t-a) = e-asF(s). Is that the line I should use? Even if it is, I don't know how.
