A second-order differential equation is given as follows: f"(t) - 9 f(t) = g(t) where g(t) is a non-continuous function represented by, g(t) = 5H(t) + H(t-1). Solve the differential equation using Laplace Transform by applying partial fraction and second shift theorem for inverse Laplace Transform, if the initial conditions are f(0) = 0 and f'(0)=1
