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 
a function? Why or why not?
What will be an ideal response?
It is a function because each x-value gives one and only one y-value. It passes the vertical line test.
