Q$2)Vcc=10V,$ D $1$ is ideal with forward drop of $1$ V $.$ The NMOS transistor is ideal and has $1\mathrm{.}5$ V of Vgs $.$ Vin, R$1$ and R$2$ are customizable.

According to your design;

a$)$ What can be the minumum and maximum voltage values at Vout?

b$)$ Plot Vin vs Vout graph to show cutoff, active and saturation regimes.
