A function is a relation which associates every element in the domain to a unique element in the codomain.

In option 1,

2 has more than one image, namely 3 and 7.

In option 3,

11 has more than one image, namely 9 and 5.

In option 4,

3 has more than one image, namely 8 and -2.

Hence, the correct option is 2, where every element in the domain has unique image.

30 POINTS FOR WHOEVER CAN SOLVE THIS!!

The two inequalities formed will be:
One for ticket quantity:
x + y ≤ 600

One for funds generated via tickets:
5x + 7y ≥ 3500

Equating x to 330,
5(330) +7y ≥ 3500
y = 265

Checking if the other inequality holds true:
330 + 265 ≤ 600
595 ≤ 600

This inequality is still true so they can sell 265 tickets on the event day and cover their expenses.
