Question

need this answered! asap please <3

Answer 1

Answer:

The first 3 are not a right answer so if there is a 4th option that one is it.

Step-by-step explanation:

You can determine whether each element of the domain is paired with exactly one element of the range. For example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

Answer 2

Answer:

None of the relations shown are a function

Step-by-step explanation:

We can use the vertical line test to determine if it is a function

Take a line that goes up and down.  If it touches 2 or more points, then it is not a function.

A is not a function because it touches 2 points at -1

B is not a function because it touches 2 points at -2

C is not a function because it touches 2 points at 0

None of the relations shown are a function
