A graph-paper doodle connects each point on the x-axis with a consecutive point on the y-axis with a straight line. Within a defined boundary, the positions on the x-axis move away from the origin as the positions on the y-axis move toward the origin. The resulting shape fills a defined curving boundary with a pretty pattern.

The geek challenge for this month is to define the curve generated by these straight lines. Focusing on the lines in the positive x and y quadrant, select the function type that describes the limiting curve assuming the pattern is drawn on a range from 0 to 1 with infinitely dense graph paper.

Which is the correct formula?
