One is to check the continuity of f (x) at x=3, and the other is to check whether f (x) is differentiable there. First, check that at x=3, f (x) is continuous. It's easy to see that the limit from the left and right sides are both equal to 9, and f (3) = 9. Next, consider differentiability at x=3. This means checking that the limit from the ... A Function Can be in Pieces. We can create functions that behave differently based on the input (x) value. A function made up of 3 pieces. Example: Imagine a function. when x is less than 2, it gives x2, when x is exactly 2 it gives 6. when x is more than 2 and less than or equal to 6 it gives the line 10−x. It looks like this:Looking at this piece of our piecewise function, clearly we need to consider our constants a and b.Since our function f is a function of x (indicated by f(x)), we can consider the other letters in this piece of our function (a and b) to be constants.I discussed this in a bit more detail here, but it basically means that a and b are some set number, …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.

When t = 1, both sides are in the domain, so the condition of continuity is. limx→1 f(x) = f(1) But for this piecewise defined function, to examine if this is true, we need to note that limx→1 f(x) exists if and only if the two one-sided limits exist and are equal.In some cases, we may need to do this by first computing lim x → a − f(x) and lim x → a + f(x). If lim x → af(x) does not exist (that is, it is not a real number), then the function is not continuous at a and the problem is solved. If lim x → af(x) exists, then continue to step 3.
