In mathematics, a critical point or stationary point of a differentiable function of a real or complex variable is any value in its domain where its derivative is 0. Some authors include in the critical points the limit points where the function may be prolongated by continuity and where the derivative is not defined.
If we do that, then f (x) will be continuous at x = 2 -- because the limit at that value will be the value of the function. (Definition 3 .). When we are able to do that -- define a function at a value where it is undefined and therefore discontinuous -- we say that the function has a removable discontinuity. (x) therefore is continuous at x = 8. (Definition 3 .). In this same way, we could show that the function is continuous at all values of x except x = 2. This is an example of a perverse function, in which the function is deliberately assigned a value different from the limit as x approaches 1.
