For each of the following ARMA models, find the roots of the AR and MA polynomials, and identify the values of p and q for which they are ARMA(p,q). Remember to cancel out the common factors of AR and MA polynomials when determining p and q. Assume that {at}t≥0 is a zero-mean unit variance white noise sequence.

The following figure represents the graph of a particular solution to ay" + by' + cy = 0. What can you say about the root(s) of the characteristic polynomial ar^2 + br + c = 0? Briefly explain your answer. A. There are distinct real roots r1, r2. B. There is a repeated real root r C. The roots are purely imaginary r = ±μi D. The roots are complex r = λ ± μi
