D) graph $A ; y = x$

Quizplus · Accepted Answer

Graph B, which is described by the equation $x = y^2$, is not the graph of a function because it fails the vertical line test. In a function for each input (x value), there must be only one output (y value). The equation $x = y^2$ can yield two y values for a positive x, meaning a vertical line can intersect the graph at more than one point, indicating it's not a function.
