Provide an appropriate response.The equation y = x2 is satisfied by the points (2, 4) and (-2, 4). A horizontal line may be drawn between these two points. Is y = x2 a function? Explain.
What will be an ideal response?
Yes. It is a function because for each x-value there is only one y-value. The relation thus passes the vertical line test. It does not have to pass the horizontal line test to be a function. (Explanations will vary.)
