What’s the answer guys?

the first one is the answer, with maybe the third if you can choose multiple.

Step-by-step explanation:

Let's go throught hese one at a time.  First though it is important to note that the poitns look like they are going upward.  So we want a relationship that it makes sense  as one increases so does the other.

the amount of money made made compared to the amount of items sold

So, pretending we run a store.  Does it make sense that if we make more money more items were sold?  I would say so.

the amoutn of ink left in a pen compared to the time using it

Doe sit make sense that as the amount of ink increases the time using it increases?  i would say no, because ink usually decreases the more it is used.

the amount of money in your account compared to the number of stores that you shop at

Does it make sense that if you have more money in your account you shop at more stores?  I think so, though the first one still makes the most sense if you can only pick one.  Since it doesn't seem directly to imply that, I would say it makes more sense that you just but more in general, not necessarily from more stores.

the number of goals scored in a soccer match compared to the number of red cards given

does it make sense that more goals would also have more red cards?  i don't think so, though I don't know soccer that much.  it doesn't seem like goals mean there should be any more red cards.

So in total it seems like the first one is the answer, with maybe the third if you can choose multiple.  

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
