(d) First, we will find the lower bound for $W(n) = 2^{n+1}-n-2$  \\  $2^{n+1}-n \geq 2^n - \frac{2^n}{2}$ which is true for $n > 2$  \\Since $\frac{2^n}{2}$ belongs to $\BigO(2^n), W(n) $\Omega(2^n)$, $W(n)$  must as well since it is less greater  than \frac{2^n}{2}$ or equal to $\frac{2^n}{2}$  \\*
