Answer 1

you have a function when for any input (x-value) there is only one output (y-value)

Answer 2

so the answer is C

Answer 3

@triciaal

Answer 4

NO it cannot be a function read again and look at x = -3 and x = -6

Answer 5

okay so then if its not C then it can not be A either right @triciaal

Answer 6

you will have a function when any chosen value of x will give the value of y following a set "formula"

Answer 7

hint
Function: A function is a set of ordered pairs in which each x-element has only ONE y-element associated with it.

Answer 8

hint:
A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair ( x , y ) is in the relation. A function is a type of relation.

Answer 9

okay so it is A
