But then it keeps goingĪnd it looks just like y equals x squared. And instead of it being three squared, at this point you have this opening, and instead the function at You see that this curve looks just like y equals x squared, until we get to x equals three. So let's first review theĬlassification of discontinuities. Relate it to our understanding of both two-sided limitsĪnd one-sided limits. When you took algebra, or precalculus, but then Types of discontinuities that you've probably seen Going to do in this video is talk about the various If you want to learn more, go to this page to see some more situations in which it's possible to do a direct substitution: However, say you found a function that is similar to the simplified function, only without the constraint, called g(x) = (x+6). The constraint is added to be mathematically correct when it comes to being equivalent to the limit beforehand. For this example, you could simply factor the limit to get lim_(x->2)_ (x+6), x ≠ 2. However, there are many ways to determine a function by simply simplifying the function when direct substitution yields the indeterminant form. For example, lim_(x->2) (x^2 + 4 x - 12)/(x - 2), determined directly, equals (0/0), indeterminant form. There is also another way to find the limit at another point, and that is by looking for a determinant for the indeterminate form by using other methods and defining it by using another function. In other words, as long as the function is not discontinuous, you can find the limit by direct substitution. A function can be determined by direct substitution if and only if lim_(x->c)_ f(x) = f(c).
