Question

Can someone please help me.
Identify the mapping diagram that represents a relation and determine whether the relation is a function {(-2,-4),(-1,-4),(3,-4),(6,-4)}

Answer 1

@pooja195 do you think you can help me with this question. I really need help and don't know who else to ask, please.

Answer 2

what makes a function is weather there are any x values repeating . So if there are x values repeating, it is not a function. And if there aren't any x-values repeating, then it's a function.
You also need to remember how to set up the table for the data by having the x variables on the left and y variables on the right.

Answer 3

okay im still somewhat confused, so the answer would be B? (the second picture) because none of the X variables are shown twice so it's a function?? @Eli_Moses

Answer 13

then you are correct and the relation is not a function

Answer 14
