How to see if a limit exists
Web10 nov. 2024 · Figure 14.2.2: The limit of a function involving two variables requires that f(x, y) be within ε of L whenever (x, y) is within δ of (a, b). The smaller the value of ε, the smaller the value of δ. Proving that a limit exists using the definition of a limit of a function of two variables can be challenging.

Web20 dec. 2024 · If f(a) is defined, continue to step 2. Compute limx → af(x). In some cases, we may need to do this by first computing limx → a − f(x) and limx → a + f(x). If limx → af(x) does not exist (that is, it is not a real number), then the function is not continuous at a and the problem is solved. If limx → af(x) exists, then continue to step 3.

This is a one sided limit coming from the right side. As you approach x = 5 from the left, f (x) = 2 again. This is a one sided limit coming from the left. cynthia tignorWebThe only way a limit would exist is if there was something to "cancel out" the x-1 in the denominator. So if you had something like [ (x+2) (x-1)]/ (x-1). Then there would be a hole at 1, but the limit would still exist, and it would be 3. This is how you have to handle most rational functions.
