Matlab 2015a programming. Coding and output needed.

c) The transfer function of a control system is defined as the ratio of the output variable to the input variable. The transfer function for a storage tank model is presented as follows: (s +1)(s + 2) s2 - 9s +18 A process is stable if the root of denominator has negative values. Determine the stability of a given process. [3 Marks]
