Option 1 is correct.

Step-by-step explanation:

Because in all the other three tables, a certain domain has two outputs { x= -5 in table 2 ; x= -2 in table 3 ; x= -4 in table 4 } which is not possible in case of a function.

Only in the first table, all the domains have only one outputs . So it is a function.

m∠a is 90°

m∠b is 40°
