**QUESTION 1** Let \( x[n] = (n + 1) 2^n \, u[n - 1] \). It is observed that its z-transform is of the form \[ X(z) = \frac{B(z)}{1 + a_1 z^{-1} + a_2 z^{-2}} \] where \( B(z) \) is some polynomial. What is \( B(4) \)? **Options:** - \( \frac{1}{4} \) - \( \frac{3}{4} \) - 3 - 4 - 12 - None of the above
