6.* Find an example of a function such that the limit exists at every x, but that has an in nite number of discontinuities. (You can describe the function and/or write a formula down and/or draw a graph.) PARTIAL ANSWERS: 1. (a) x = 0;3 (b) x = 2;0;1 2. (a) R (b) Rnf 1=2;2g (c) (1 ;5] (d) ( 3;2)[( 2;2)[(2;4) 3.
13 Φεβ 2019 · 1. How do you read f(x)? Solution: \F" of \X." 2. How do you read lim f(x) = L? x!a. Solution: The limit of \F" as \X" approaches \A" is \L." 3. How do you read lim. x!a. f(x)? Solution: The limit of \F" as \X" approaches \A" from the left. 4. How do you read lim f(x)? x!a+. Solution: The limit of \F" as \X" approaches \A" from the right.
Let be a function defined on the interval [-6,11] whose graph is given as: The limits are defined as the value that the function approaches as it goes to an x value. Using this definition, it is possible to find the value of the limits given a graph. A few examples are below:
Limits are the machinery that make all of calculus work, so we need a good understanding of how they work in order to really understand how calculus is applied. 1.1 Formal De nition. De nition: Let f(x) be de ned on an open interval about c, except possibly at c itself.

CALCULUS AB WORKSHEET 1 ON LIMITS. Work the following on notebook paper. No calculator. 1. The graphs of f and g are given. Use them to evaluate each limit, if it exists. If the limit does not exist, explain why. ( a ) lim ⎡ ⎣ f ( x g ( x. x → 2. ( ) c lim ⎡ f x g x ⎤. x → 0 ⎣ ( ) ( ) ⎦. ( b ) lim f. → 1 ⎡ ⎣ ( x g ( x ) ⎤ ⎦. ( x ) lim ( )
1. The limit of a function as x tends to infinity. If we have a sequence (yn)∞ n=1, we can say what it means for the sequence to have a limit as n tends to infinity. We write yn → l as n → ∞ if, however small a distance we choose, yn eventually gets closer to l than that distance, and stays closer. We can also write lim f(x) = l . x→∞.
