My initial answer was C. But, i found that if you choose y=1 and z=2, you aren’t able to use the rule stated in the question as it will be negative. So is the answer D ?
It’s defining an operation and its “domain”. So your example is not something the operator can act on cuz of the domain restriction.
so is the answer C or D ?
Should be D yeah cuz you can’t compare the two quantities for some values of y and z (one of which u showed) even though they’re part of the constraints established in the question.
