Dora said that the mapping diagram below does
not represent a function because each value in
the domain is paired with the same value in the
range. explain the error in dora's reasoning.

I don’t see any graphs. Try copying android pasting images.
Step-by-step explanation:
C
Step-by-step explanation:
x2+y2=9 is an example of a non function because there is at least one x value with two or more y values .
i have no idea i think its 0.5 or 12
Step-by-step explanation:
C
Step-by-step explanation:
c
Step-by-step explanation:
Because X (10) repeats
Step-by-step explanation:
A function has no repeated X but here in your x variable 10 is there twice so therefore it is NOT a function
You can use the pencil test also in a graph, align your pencil vertically and see if there are multiple points that have the same X and if there isn't any repeated its a function.
C.The points where a vertical line intersects a graph have the same x-value but different y-values. The graph of a function cannot have points with the same x-value but different y-values.
Step-by-step explanation:
It is like I have said before. Repetitive x-values indicate no functions.
I am joyous to assist you anytime.
0,0
Step-by-step explanation:
The function set is empty
Option 2
Step-by-step explanation:
if an input produces more than one output, the table does not represent a function.
A) [tex]x = y^{2}[/tex]
Step-by-step explanation:
An equation is a function of [tex]x[/tex] when [tex]x[/tex] is the independent variable, that is:
[tex]y = f(x)[/tex](1)
Where [tex]y[/tex] is the dependent variable.
According to this, [tex]x = y^{2}[/tex] does not represent a function of [tex]x[/tex], since the independent variable is a function of [tex]y[/tex], that is, [tex]x = f(y)[/tex]. Therefore, the correct answer is A.
