Can someone help me please? Give the domain and range. Tell if it is a function

I think the answer is #4

Step-by-step explanation:

Because each Domain only goes to one Range, so it is a many-to-one Function. And I believe that you only need to label each range that was used once.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
