Best ResponseYou've already chosen the best response.2Imagine you're walking on the graph, towards x=2, from the right side : dw:1438030518779:dw

Best ResponseYou've already chosen the best response.2what value does the graph takes as you approach x=2 ?

Best ResponseYou've already chosen the best response.2careful, values down that horizontal axis are negative so i think you mean 2 ?

Best ResponseYou've already chosen the best response.2Yes, so we say the limit from right hand side of x=2 is \(2\) and we write it mathematically as : \[\Large \lim\limits_{x\to2^{+}}~~f(x)~~~=2\]

Best ResponseYou've already chosen the best response.2see if you can guess the limit from left hand side : \[\Large \lim\limits_{x\to2^{\color{red}{}}}~~f(x)~~~= ?\]

Best ResponseYou've already chosen the best response.1And if you notice f is approaching 2 if you plug in values to the right of x=2 like f(2.5)=2 f(2.3)=2 f(2.1)=2 These numbers don't all usually appear the same but these numbers are approaching 2 as x approaches x=2 you can do the same thing for the left... also I know f(2.1)=2 from just looking at: dw:1438031090291:dw

Best ResponseYou've already chosen the best response.1and also I probably could have drawn 2.1 closer to 2 but it is kind of hard to draw it closer to 2.1 without making it ugly and not readable
