QUESTION 15 Let g [n] be the following sequence: 4-3-2-1 0 1 Consider the sequence y(n]=x[n+2]-2g[n+1]*x[n-21+3x[n]+4x [n+1]. Can we equivalently write that y(n]=f[n]*x [n] for some sequence f[n]? Yes, and we must have f[-1]=-2 Yes, and we must have f[-1)=0 Yes, and we must have f[- 1]=3 Yes, and we must have f[ –1]=4 Yes, but there is not enough information to specify f[-1]. No None of the above he
