Determine which of the following are functions. select all that apply

I still need the whole question to answer it correctly .

Step-by-step explanation:

to determine a fonction a will give you an example .

(2,3) (2,3) (3,5) (8,9)

a) is f(2)

B) is f(4)

C) is f(3)

so in this case the answer would be 4 because 4 is not repeated on the first fonctions which are 2,2,3 and 8.

I don't know if your question is this case but I hope this helps.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
