HELP 40 POINT!!! PLEASEIs the relation a function?Select Yes or No for each relation.1. (−2,1),(−4,−2),(3,1),and(8,9)2. (−2,1),(−4,−2),(3,−2),and(8,6)3. (−2,6),(−4,3),(3,−2),and(8,6)4. (3,−9),(−4,1),(3,−2),and(5,6)

1. Yes this is a function since the x coordinates do NOT repeat. Each x value leads to exactly one y value.

2. Same thing as problem 1. This is a function.

3. Same thing as the previous two problems. This is a function.

4. This is NOT a function because we have the input x = 3 lead to the outputs y = -9 and y = -2 at the same time. The input x = 3 must have exactly one output for a function to be possible.
