Question 8: To confirm this, show that f( p ) ly()) = f(p(t) ly(t), y(t-1)) _ f(y) [p())f(p()ly*-1) fly (t ) ly (t-1) ) (7) You need to detail your reasoning to obtain this equation. Note that the denominator on the right-hand side of Eq. (7) does not depend on p(), i.e. f(p()ly(*)) is proportional to f(y(t)(p(t) ) f(p(t) lyt-1). (1 Mark)
