WebJul 12, 2024 · Because the value of f does not approach a single number as x gets arbitrarily close to 1 from both sides, we know that f does not have a limit at a = 1. Since f does approach a single value on each side of a = 1, we can introduce the notion of left and right (or one-sided) limits. WebJan 18, 2024 · With right-hand limits, the limit will not exist if the value for the f (x) continuously moves toward infinity as values for x inputs continuously approach the value for c.
