How do I complete this AR(p) model?

Assume the AR(p) model: Yt = ao + aiyt-i + et Given the coefficients below, are each of the combinations stationary? If so, to what value do they converge? (Take values out to 4 decimal places) ai -1 az 0 Stationary? If yes, converges to a b -1 az 0 0 0 0 0 C -1 d ao 0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.5 e f -0.5 0.5 1 -0.8 0.8 0.5 0.5 0 -1 0 1.5 1.5 -0.5 -0.5 -1 1 0 h i 0.5 -0.5 0.5 0.8 Assume the AR(p) model: Yt = ao + aiyt-i + et Given the coefficients below, are each of the combinations stationary?
