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.
