I need some help doing this problem related to MOS Transistors. How do you recommend going about doing this? All your help is appreciated! Thanks so much

Find the minimum and maximum possible values of Vds for the MOS transistor when used in the

circuit below. The only variable is the transistor gate ( 0 ohms to 10 kΩ).
