Best ResponseYou've already chosen the best response.2well... find the onesided limits for the piecewise function if the \(\bf \lim\limits_{x\to 0^}\textit{ is equal to }\lim\limits_{x\to 0^+} \\ \quad \\ then\qquad \lim\limits_{x\to 0}\ exist\)

Best ResponseYou've already chosen the best response.2\(\large \lim\limits_{x\to 0}\qquad \begin{cases} 7x^2&x<0\quad \textit{left side, thus } \lim\limits_{x\to 0^}\\ 7&x=0\\ 10x+7&x>0\quad \textit{right side, thus } \lim\limits_{x\to 0^+} \end{cases}\) that is, if the leftside of the "limit" matches the rightside of the "limit" in this case those 2 equations, (notice the limit occurs when "x" approaches 0) then the doublesided limit exist and is THAT

Best ResponseYou've already chosen the best response.2very simple if you simply set x = 0 for those equations btw

Best ResponseYou've already chosen the best response.2well... is a piecewise, so there are 3 equations there.. so... which one did you set to 0?

Best ResponseYou've already chosen the best response.2\(\bf \lim\limits_{x\to 0^}\quad 7x^2=?\impliedby \textit{left side limit} \\ \quad \\ \lim\limits_{x\to 0^+}\quad 10x+7=?\impliedby \textit{right side limit} \) say... what would you get for those two?

Best ResponseYou've already chosen the best response.2ok... so, the leftsided limit gives 7 the rightsided limit gives 7 then \(\bf \lim\limits_{x\to 0} \implies 7\) :)
