Consider the time series given by y_t = a₁y_t-1 + a₂y_t-2 + ε_t. Where ε_t is independent white noise and y_t is stationary.

A. Compute the mean of y_t. E(y_t)

B. Compute the variance of y_t. E[y_t − E(y_t)]²

C. Compute the first three autocovariances for y_t. (E[(y_t −E(y_t))(y_t₋_i −E(y_t₋_i))] i=1,2,3).
