Question

Which graph does NOT represent y as a function of x? A) Answer choice A B) Answer choice B C) Answer choice C D) Answer choice D

Answer 1

"A" because two sides of the line are one the same x-axis. (I'm really bad at explaining )

Answer 2

Using the definition of a function, it is found that graph A does not represent a function.

---------------------------------

• The definition of a function is that one value of the output is attributed to each value of the input.
• If a value of the input is related to more than one output, it will not be a function.
• In a graph, the input is x and the output is y.
• Looking at the graphs given, it can be seen that in graph A, for values of $x > 0$, there are 2 values of y, that is, two outputs are mapped to one input, which means that it is not a function.
