PS 9.4c

First of all, is the identical gate referring to the circuit in the the
slide?

If that is the case, this question makes no sense. The slide circuit
only produces two possible outputs from the set of all inputs - neither
of which are 1 V.

The thought process behind this circuit is that if you add a load device,
current could flow from that device into the first. If the first device
is trying to drive current through R2 to reduce the output voltage, this
incoming current will lower the current through R2 and raise the output
voltage.

I suppose the problem should read
"Find the maximum value where the circuit could still have an output below
Vout = 1V for some input."

Hope this helps,
