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
21 Δεκ 2020 · In Exercises 13-21, evaluate the given limits of the piecewise defined functions \(f\). 13. \(f(x) = \begin{cases} x+1 \quad &x\le 1\\ x^2-5 &x>1 \end{cases}\) (a) \(\lim\limits_{x\to1^-}f(x) \)
Practice. Limits of Functions: Problems with Solutions. Problem 1. Select the value of the limit \displaystyle \lim\limits_ {x\rightarrow 0} \frac {1} {x}\times \left (\frac {1} {x+4}-\frac {1} {4}\right) x→0lim x1 ×(x+41 − 41) \displaystyle -\frac {1} {16} −161. \displaystyle -\frac {1} {8} −81. \displaystyle \frac {1} {16} 161.
Practice with Limits. Here are some problems to practice what you have learned! If you need a hint on any of them, there's a few for each problem. Self-paced high school math material, explained to be understood.

Practice Problems on Limits and Continuity 1 A tank contains 10 liters of pure water. Salt water containing 20 grams of salt per liter is pumped into the tank at 2 liters per minute. 1. Express the salt concentration C(t) after t minutes (in g/L). 2. What is the long-term concentration of salt, i.e., limt!¥ C(t)? Solution: 1.
