3. For the system below, use the root locus (drawn using MATLAB) to find the range of proportional gain values for which the closed-loop system will be stable. (Hint: when you place a tooltip on the root locus, you can read off the gain values and location of the pole) [4] $G(s) = \frac{s^2 + 2s + 4}{s(s+4)(s+6)(s^2 + 1.4s + 1)}$
