👉 In mathematics, a semistiffly function is a type of continuous function that can be represented by a single variable, such as x. This means that it has no critical points (points where the function changes its value), and instead has a fixed point, which is an interior point of the domain. For example, consider the function f(x) = 2x^3 - 3x^2 + 4x - 5. This function does not have any critical points since
