Algebra-net.com brings great information on turning point of a hyperbola excel, arithmetic and decimals and other math subjects. Not all points where dy dx = 0 are turning points, i.e. Point A in Figure 1 is called a local maximum because in its immediate area it is the highest point, and so represents the greatest or maximum value of the function. However, stationary points are not always turning points, see stationary points of inflexion like the one below: Thanks for contributing an answer to Mathematics Stack Exchange! The next point that we hit is the \(x\)-intercept at \(x = 2\) and this one crosses the \(x\)-axis so we know that there won’t be a turning point here as there was at the first \(x\)-intercept.
