Tap for more steps. Y x2 9 y x 2 9. This calculus video tutorial explains how to find the point where the graph has a horizontal tangent line using derivatives. If f x y x 2 y then f x 2 xy boundary.

That s because it s quite possible for an equation to pass the vertical line test but not the horizontal line test. Find the horizontal tangent line y x 2 9. The rise is the distance you go up the vertical part of a stair step and the run is the distance you go across the horizontal part of a step.
