How to find continuity of a piecewise function.

It’s also in the name: piece. The function is defined by pieces of functions for each part of the domain. 2x, for x > 0. 1, for x = 0. -2x, for x < 0. As can be seen from the example shown above, f (x) is a piecewise function because it is defined uniquely for the three intervals: x > 0, x = 0, and x < 0. In its simplest form the domain is all the values that go into a function, and the range is all the values that come out. Sometimes the domain is restricted, depending on the nature of the function. f (x)=x+5 - - - here there is no restriction you can put in any value for x and a value will pop out. f (x)=1/x - - - here the domain is restricted ...Porsche has partnered with Mobileye to bring hands-free automated assistance and navigation functions to future sports cars.

It means that the function does not approach some particular value. Take sin (x) for example. It is defined for any x, but the limit of sin (x) as x goes to infinity does not exist, because it doesn't get closer to any value; it just keeps cycling between 1 and -1. Or take g (x) = (1/x)/ (1/x). It is not defined at 0, but the limit as x ...

Solution: We separate into 3 cases: x<0, x>0 and x = 0. For the first two cases, the function f(x) is defined by a single formula, so we could just apply di↵erentiation rules to di↵erentiate the function.
