A unity feedback system has a forward transfer function of G(s) = following: a. Sketch the root locus (MATLAB plot inspection allowed). b. Find the asymptotes. K(+1) s(3+2)(S+3)(5+4)* Do the c. Find the value of the gain that will make the system marginally stable. d. Find the value of the gain for which the closed-loop transfer function will have a pole on the real axis at -0.5.
