*Limits of Functions 3. The limit of a function as x tends to a real number There is one more type of limit that we can deп¬Ѓne for functions. Let us consider the function f(x) = x+3. If we choose a number, such as 1, then as x gets closer and closer to that number, f(x) also gets closer and closer to a number, in this case 4. We write f(x) в†’ 4 as x в†’ 1, or lim xв†’1 f(x) = 4.*

We have studied linear functions and power functions in Section 2.1 and Section 2.2, respectively.Now let u = u(x,y) be a real-valued function of the two real variables x and y.Recall that u has the limit as approaches provided that the value of can be made to get as close as we please to the value by taking to be.

The reason that the limit is 9 is that our new function f(x) coincides with our old continuous function g(x) for all xexcept x= 3. Therefore the limit of f(x) as x!3 is the same as the limit of g(x) as x!3, and Infinite Limits. Evaluating the limit of a function at a point or evaluating the limit of a function from the right and left at a point helps us to characterize the behavior of a function around a given value. As we shall see, we can also describe the behavior of functions that do not have finite limits.

The limit of a function f(x) as x approaches p is a number L with the following property: given any target distance from L, there is a distance from p within which the values of f(x) remain within the target distance.

The proofs of these theorems are pretty much identical to that for real functions, so we will omit their proofs for now.
