1. Which of the following represents a function?

Answer 1

c i think

Answer 2

ya im not too sure but im kinda thinking b or c

Answer 3

functions are either one-to-one or many-to-one

that means for a one-to-one there is only one value of y for every value of x

many-to-one : there maybe 2 or more values of x for one value of y


but a one-to-many relation is NOT a function

for example if you had more than y value of y for one value of x

Answer 4

for example:- a is not a function because x = -1 maps to 3 and also maps to 5
