Practice problems on limits and continuity 1 a tank contains 10 liters of pure water. Similar definitions can be made to cover continuity on intervals of the form and or on infinite intervals.
No reason to think that the limit will have the same value as the function at that point. Limits, continuity, and the definition of the derivative page 3 of 18 definition continuity a function f is continuous at a number a if 1 f a is defined a is in the domain of f 2 lim xa f x exists 3 lim xa f xfa a function is continuous at an x if the function has a value at that x, the function has a. Express the salt concentration ct after t minutes in gl. Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu. Complete the table using calculator and use the result to estimate the limit. We will use limits to analyze asymptotic behaviors of functions and their graphs. My only sure reward is in my actions and not from them. The function is not continuous at x 0, because it is defined at that point.

Use the graph of the function fx to answer each question. Provided by the academic center for excellence 1 calculus limits november 20 calculus limits images in this handout were obtained from the my math lab briggs online ebook. Find the following limits involving absolute values. You should already know the information on these limits worksheets cn pg 3. If r and s are integers, s 0, then lim xc f x r s lr s provided that lr s is a real number. We shall study the concept of limit of f at a point a in i. Questions with answers on the continuity of functions with emphasis on rational and piecewise functions. The limit of a rational power of a function is that power of the limit of the function, provided the latter is a real number.
Limits will be formally defined near the end of the chapter. Here we are going to see some practice questions on limits and continuity. The continuity of a function and its derivative at a given point is discussed. Intuitively, we can argue that, if n is very large, then the largest term sometimes called. Is it possible for this statement to be true and yet f 25. We will now take a closer look at limits and, in particular, the limits of functions. Limits are used to define continuity, derivatives, and integral s. Our limits and continuity worksheets are free to download, easy. About limits and continuity worksheet with answer limits and continuity worksheet with answer. Create the worksheets you need with infinite calculus. A function f is continuous at x a provided the graph of y fx does not have any holes, jumps, or breaks at x a. For problems 3 7 using only properties 1 9 from the limit properties section, onesided limit properties if needed and the definition of continuity determine if the given function is continuous or discontinuous at the indicated points.
We say lim x a f x is the expected value of f at x a given the values of f near to the left of a. Limits may exist at a point even if the function itself does not exist at that point. Analyze functions for intervals of continuity or points of discontinuity determine the applicability of important calculus theorems using continuity click here, or on the image above, for some helpful resources from the web on this topic.
