Plz hurry! which mapping diagram represents a function from x → y?

OPTION A

OPTION C

Step-by-step explanation:

A relation becomes a function when it satisfies the following two conditions:

(i) Any element from the domain can only be mapped to only element in the co-domain.

(ii) No element in the domain should be left unmapped.

Note that an element in the co-domain need not have a pre - image.

OPTION A: Every element has an image and no element is mapped to two different elements on the co - domain. so, it is a function.

OPTION B: The element 9 is mapped to both 4 and 6. Condition (1) is not satisfied. So, it is not a function.

OPTION C: Both the conditions of a function are satisfied. So, OPTION C is a function. Note that the element 8 in the co - domain does not have a pre - image but it is still a function.

OPTION D: Element 1 in the domain is mapped to two elements. Violation of Condition (i). So, it is not a function.

the solution is 12x-6y

the correct answer is x/3+10≥32

hope this !
