Limits: getting close to a number
Fill in a table of values close to a point where a function is undefined, read the limit from the graph, and see why the left-hand and right-hand limits must agree.

الدليل
A limit asks: as x gets close to a number (without reaching it), which number does f(x) get close to? It is not the same as the value of the function at that point; the function may not even be defined there.
You can approach from two sides: from the left (the النهاية من اليسار) and from the right (the النهاية من اليمين). If both reach the same number, that number is the limit. If they differ, the limit does not exist.
