If someone were to ask, "For what values of x is f continuous?" then I know that I would answer this, because f is discontinuous at 0 and 5:īut if someone were to say "Describe the intervals on which f is continuous," then how can I possibly dispute it if a student answers this? Thus, by definition of continuity on a closed interval, f is continuous on the closed interval, since it is continuous on the open interval (0,5), continuous from the right at 0, and continuous from the left at 5.
The definition of "f is continuous on the closed interval " is that f is continuous on (a,b) and f is continuous from the right at a and f is continuous from the left at b. We show existence of a minimizer of the regularized inverse problem. Both interface identification and reconstruction of piecewise constant coefficient values are considered. The definition of "f is continuous from the left at b" is: We consider a discontinuous coefficient reconstruction problem associated with a variable-order time-fractional subdiffusion equation. condlistlist of bool arrays or bool scalars. Given a set of conditions and corresponding functions, evaluate each function on the input data wherever its condition is true. Thus f is continuous from the right at 0. numpy.piecewise(x, condlist, funclist, args, kw) source. Enter a problem Save to Notebook Sign in. A function basically relates an input to an output, there’s an input, a relationship and an output. The definition of "f is continuous from the right at a" is: Explore piecewise functions step-by-step piecewise-functions-calculator. I know that f is not continuous at 0 or at 5.
