comment Is there a specific name for this set of square-rooted primes?
Thank you for your answer. How about the invertiblity property. Also, it seems to me that its not exactly like the group of the integers under addition as this prime-root set has certain "fundamental" elements. Is there a formal definition/name for this property that you are aware of? Thanks again :)

Just stating, I greatly edited my answer as some things in it were plainly wrong / convoluted.

Honestly, I fear that you have not tried hard enough as the answer very readily follows from the hints you have been given. Give it another try :) really think what it means to have squares.

intersections: (0,0), (-2,2) and (2,2), so A = 4*2*0.5 = 4 units.

comment Interpolating polynomial given only Y values
Gawd.. now that I wrote so much, I'd really like to know how you got to this question anyways :) You got me curious!

comment Interpolating polynomial given only Y values
Also, in my first comment I said that given any number of points, a lagrange polynomial can be constructed… It should state: "given any number of points, none of which that the same x-coordinate but differing y-coordinates, a Lagrange polynomial can be constructed". Other wise the resultant "thing", if it could be made, wouldn't even be a function. Also I meant "The constraint simply makes sure that at certain x-points, our polynomials must have HEIGHTS y an z" - my bad. Hope all this helped.

comment Interpolating polynomial given only Y values
So this completes the answer. So given 2 sets of y and z heights with the same x coordinates, we can construct infinitely many pairs of polynomials of the same degree (starting with a degree of 2d) which at any of the given x points (from the data sets), will have heights of y and z. As there are no unique polynomials to interpolate the data points, there are no unique roots that can be derived from the given data, we will need more constraints to be able to produce such things.
