Referring to the two markets in the Orange Inc. noise cancellation headphone example and the estimated Bass model:

Market $1-$S$($t$)=2\mathrm{.}43+0\mathrm{.}427$ Y $(+-1)-0\mathrm{.}0058$ Y$($t$-1)2$

Market $2$: S$($t$)=4\mathrm{.}92-0\mathrm{.}091$ Y $(+-1)-0\mathrm{.}0037$ Y$(+-1)?$

Which of these two markets does not follow a standard product life cycle? Describe in words, the shape of the sales curve over time. There is no need to draw, simply explain why you expect this sales curve shape, and what is predicted sales in the first period for this market?
