An equation of this line is given by y x 2 To the right of and including x 0 the graph is part of the line passing through 0 0 and 2 2 . Okay so piecewise functions can typically occur in as many regions as possible often times you don 39 t really deal with anything more than 2 or 3 but in theory we could have a piecewise graph that has 20 different regions and it would still be acceptable. If the two one sided limits had been equal then 2 lim x gx would have A piecewise function may have discontinuities at the boundary points of the function as well as within the functions that make it up. 3 We see that if a function is differentiable at a point then it must be continuous at that point. Piecewise functions are special functions that have different parts Chapter 2. series limit abs and signum can handle the piecewise function. Limits of piecewise functions A piecewise function is a function of the form f x g x x gt a h x x a If both g x and h x are polynomial functions the only place that might trip you up is if we are evaluating the limit at x a.
