Answer: the addition of xy would make it a polynomial because it cannot simplify and the equation would have 3 different set of numbers that could not combine.
Step-by-step explanation:
(i) From the graph value of x varies -3 to 3 i.e.

and domain in the input values which function can take
So, option (d) is correct.
(ii) option (d) is correct as it represent the function
. While all the other function does not satisfy the given conditions.
(iii)
are the parts of solution pair.
(iv) Option (c) and (d) represents the function as each element of the first set has a unique image in the second set.
