y[n+2]+2y[n+1]+y[n]=x[n]

=> y[n+2] = - 2 y[n+1] - y[n] + x[n]

  • " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
