Question 12 Select the correct statement about the root locus of the following system: R(s) + K(s + 1) s2 + 5s + 17.33 C(s) O None of them are correct. O When K goes to +o, two branches of the root locus end at -1 and one remaining branch goes to infinity approaching an asymptote. O For K = 0, the root locus begins at s=-1 and when K goes to +co, two branches go to infinity approaching asymptotes. O The root locus has three branches and point s=-2 on the real axis belongs to the root locus. The root locus has two branches and point s=-0.2 on the real axis belongs to the root locus.
