Step-by-step explanation:
(i) From the graph value of x varies -3 to 3 i.e.
[tex]-3\leq x\leq 3[/tex]
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 [tex]y=x[/tex]. While all the other function does not satisfy the given conditions.
(iii) [tex](-14,-15), (-9,-10)[/tex] 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.
