Answer all questions by showing the code of matlab

The transfer function of the system is given by 1 G(S) = 5- +3s +4 You were asked to analyse the open-loop performance and an uncompensated feedback control response of the system before an appropriate controller is proposed to improve the transient and steady-state performance. For that, you are required to write a MATLAB code to obtain the steps below: 1. Obtain the open-loop transfer function of the system. 2. Plot the step response
