Sep 9, 2015 · Here are four examples... x The simplest example of an unbounded function is f (x) = x, which is unbounded for x in (-oo, oo) 1/x The function f (x) = 1/x is unbounded on any interval that includes x = 0, due to a simple pole at x = 0. tan (x) The function f (x) = tan (x) is unbounded on any interval that includes an x of the form pi/2 + npi ...
Answer: Boundedness is about having finite limits. In the context of values of functions, we say that a function has an upper bound if the value does not exceed a certain upper limit. More... Explanation: Other terms used are "bounded above" or "bounded below". For example, the function f (x) = 1 1 + x2 is bounded above by 1 and below by 0 in that:
Apr 25, 2017 · See explanation. Definitions: A set is bounded above by the number A if the number A is higher than or equal to all elements of the set. A set is bounded below by the number B if the number B is lower than or equal to all elements of the set. Examples: Example 1 A set of natural numbers NN is bounded below by the number 0 or any negative number because for all natural numbers n we have: 0<=n and for every negative number N we have N<=n Example 2 Let A be a set A={1/n: n in NN} This set can ...
Oct 27, 2014 · 1 Answer. Reginaldo D. Oct 27, 2014. A function f is bounded in a subset U of its domain if there exist constants M,m ∈ R such that. m ≤ f (x) ≤ M, for all x ∈ U. For example, f (x) = sin(x) is bounded in R because. −1 ≤ sin(x) ≤ 1, for all x ∈ R. 2. f (x) = x2 is bounded in [0,1] because.
Sep 18, 2015 · It's undefined. 1/0 = "undefined" You tend to see "does not exist" when you encounter imaginary numbers in the context of real numbers, or perhaps when taking a limit at a point where you get a two-sided divergence, such as: lim_ (x->0^+) 1/x = oo lim_ (x->0^-) 1/x = -oo Therefore: lim_ (x->0) 1/x => "DNE" graph {1/x [-10, 10, -5, 5]} This ...
Sep 24, 2015 · Explanation: The feasible region is shown below. (Desmos graphing utility.) The feasible region is the set of all points whose coordinates satisfy the constraints of a problem. For example, for constraints: x >= 0, y >= 0, x+y <= 6, y <= x+3 The feasible region is shown below. (Desmos graphing utility.)
Graphically, limits do not exist when: there is a jump discontinuity. (Left-Hand Limit ≠ Right-Hand Limit) The limit does not exist at x = 1 in the graph below. there is a vertical asymptote. (Infinit Limit) (Caution: When you have infinite limits, limits do not exist.) The limit at x = 2 does not exist in the graph below.
May 9, 2016 · May 9, 2016. The function, as given, is not continuous at 0 as 0sin(1 0) is not defined. However, we may make a slight modification to make the function continuous, defining f (x) as. f (x) = {xsin(1 x) if x ≠ 0 0 if x = 0. We will proceed using this modified function. Using the ε −δ definition of a limit, we must show that for any ε> 0 ...
Sep 25, 2014 · A definite integral can be found on the TI-84 by 2 methods. This can best be described by using an example. int_0^5xdx Method 1: Press the MATH button Press 9 to get to the definite integral function Use the arrow key to move the cursor Enter the boundaries and function Press ENTER to get the result Method 2: Visual Press the Y= button Enter the function Press the GRAPH button Press 2ND button Press TRACE button Press 7 to get to the integration function Enter the Lower Limit In this example ...
May 1, 2018 · A closed interval necessarily includes the endpoints, such as [1,2]. If either of the ends of the interval is infinite, we know that we have to write it as open (or half closed), such as [1,∞) or (−∞,∞). This means that an unbounded (i.e. including ±∞) cannot be closed. No. A closed interval necessarily includes the endpoints, such ...
