does y = x represent a function? help now please
yes it does
Yes, the equation y = x represents a function. To determine this, we can apply a simple test known as the vertical line test.
In a Cartesian coordinate system, graph the equation y = x by plotting points. For various values of x, find the corresponding values of y and plot those points on the graph. You will notice that every vertical line intersects the graph at exactly one point.
This demonstrates that for every input value of x, there is exactly one output value of y, satisfying the criteria of a function. Therefore, y = x represents a function.
