Remember that continuity is only half of what you need to verify — you also need to check whether the derivatives from the left and from the right agree, so there will be a second condition. Maybe that second condition will contradict what you found from continuity, and then (1) will be the answer.A function could be missing, say, a point at x = 0. But as long as it meets all of the other requirements (for example, as long as the graph is continuous between the undefined points), it’s still considered piecewise continuous. Piecewise Smooth. A piecewise continuous function is piecewise smooth if the derivative is piecewise continuous.A function could be missing, say, a point at x = 0. But as long as it meets all of the other requirements (for example, as long as the graph is continuous between the undefined points), it’s still considered piecewise continuous. Piecewise Smooth. A piecewise continuous function is piecewise smooth if the derivative is piecewise continuous.Now f f is continuous at R R \ 0 0, if g g and h h are continuous there as well. And they are, since g g and h h are continuous everywhere in their domain. Therefore f(x) f ( x) is continuous on the interval R R \ 0 0. limx→0 f(x) = f(0) = f(a) lim x → 0 f ( x) = f ( 0) = f ( a) Which is true by the definition of f f.Sep 6, 2017 · So you have to check the continuity of each component function.

Hence, differentiability is when the slope of the tangent line equals the limit of the function ...If you are looking for the limit of a piecewise defined function at the point where the function changes its formula, then you will have to take one-sided limits separately since different formulas will apply depending on which side you are approaching from. Here is an example. For the following piecewise defined function f(x)={(x^2 if …

Specifically, the limit at infinity of a function f(x) is the value that the function approaches as x becomes very large (positive infinity). what is a one-sided limit? A one-sided limit is a limit that describes the behavior of a function as the input approaches a particular value from one direction only, either from above or from below.
