Question

2. Determine which of the following relations is a function. (Lesson 1-7)
F{-4,3), (-2,-2), (0, 2), (0,5)}
G{(-3, 1), (-3, 3), (-2,-1),(0,5)}
H(-4,-1),(-2,-1),(-1,-1), (3, 3)
J{(2, -5),-1,-1),(0,4), (2, -3)

Answer 1

Answer:

H

Step-by-step explanation:

H is the answer because in the simplest and easy way I can explain this is that it does have the same x in the table. If you look at F the x 0 repeats twice in the third and forth point. If you look at G the x -3 repeats twice in the first and second point. If you look at J the x 2 repeats twice in the first and forth point. The only answer choice does repeats any of the x's is H with the x's of -4, -2, -1, and 3. So with this being said H is the answer.

The y can repeat as a function just not the x.
