Determing the intervals on which a piecewise function is continuous.Constructing approximations to the piecewise continuous functions is a very natural application of the designed ENO-wavelet transform. One simple way is to use the low frequencies fj ( x) to approximate f ( x) directly. Here, we use some 1-D numerical examples to illustrate the approximation abilities of the ENO-wavelet transforms.$\begingroup$ Yes, you can split the interval $[-1,2]$ into finitely many subintervals, on each of which the function is continuous, hence integrable. There may be finitely many points where the function is discontinuous, but they don't affect the value of the integral. $\endgroup$ –

A real-valued univariate function y= f (x) y = f ( x) is said to have an infinite discontinuity at a point x0 x 0 in its domain provided that either (or both) of the lower or upper limits of f f goes to positive or negative infinity as x x tends to x0 x 0.

For each region or interval, the function may have a different equation or rule that describes …

Using the Limit Laws we can prove that given two functions, both continuous on the same interval, then their sum, difference, product, and quotient (where defined) are also continuous on the same interval (where defined). In this section we will work a couple of examples involving limits, continuity and piecewise functions.The idea about the existence of the limit of a function at any value "p" is that the one sided limits as x -> p are equal. If we make the graph of the combined functions showed in the video we will see that the one sided limits are equal in the first and third case but not in the second. There will be a discontinuity when the limit doesn't ...

Plot of the piecewise linear function = {+. In mathematics, a piecewise-defined function (also called a piecewise function, a hybrid function, or definition by cases) is a function whose domain is partitioned into several intervals ("subdomains") on which the function may be defined differently. Piecewise definition is actually a way of specifying the …I have to explain whether the piece-wise function below has any removable discontinuities.
