The polynomial functions, exponential functions, graphs of sin x and cos x are examples of a continuous function over the set of all real numbers. What is Piecewise Continuous Function? A continuous function is said to be a piecewise continuous function if it is defined differently in different...
If you compose such a function with a path on which the function is constant, then the result is a constant function from (an interval of) the reals to {0,1}, which is continuous. Here the y-axis lies entirely within the region in which f = 0. There are, of course, points ...

To determine whether a piecewise function is continuous or discontinuous, in addition to checking the boundary points, we must also check whether each of the functions that make up the piecewise function is continuous.How To: Given a piecewise function, determine whether it is continuous. Determine...
Limits and continuity of piecewise functions. In each case, provide a specific value for a (and a specific value for b, when appropriate) to ensure that each piecewise-defined function is continuous at x=1. The " a " in one prob...
Piecewise Functions: Continuity Consider a piecewise function given as f(x)={g(x), x≠ah(x), x=a. In order to see whether the function is continuous at point x=a: We have to find the limit from the left of the point x=a Similarly, identify the limit ...
Continuity in Piecewise Functions: Continuity at points where the piecewise function changes expression depends on the limit of the function at the point and the value of the function at the point. In this case the side limits are calculated with different functions, o...
This means that g is actually continuous at x=0, even though it was cobbled together in piecewise fashion. In the problem of limit, we can substitute the value of x, because the continuity connects the "near" with the "at". For example, ...
Estimates of Functions, Orthogonal to Piecewise Constant Functions, in Terms of the Second Modulus of ContinuityThe paper is devoted to the problem of finding the exact constant W2 in the inequality ‖f‖ ≤ K ω2(f, 1) for bounded functions f with the property∫kk+1f(x)dx=0,k∈. Our...
Determine whether the piecewise function f(x)= -2x + 3, if x is less than 1; x^2, if x is greater than and equal to 1, is continuous at x = 1 or not by using the definition of continuity. For what value of c ...
