limit of |x-2\/x-2 as x approaches 2. would the limit be 0?
so it looks like your function is a little messed up
not clear to me what the function is.
ill write it out better hold on
\[\lim_{x \rightarrow 2}\frac{|x-2|}{x-2}\] ?
aaah i thought as much. no limit
yeah you are correcy myinninaya.
correct*
this is a piecewise function. it is 1 if x > 2, -1 if x < 2
\[x>2=>|x-2|=x-2, x<2=>|x-2|=-(x-2)\]
and so the limit from the right is 1, the limit from the left is -1, and since those numbers are not the same the limit does not exist
\[\lim_{x \rightarrow 2^-}\frac{-(x-2)}{x-2}=-1\]
\[\lim_{x \rightarrow 2^+}\frac{x-2}{x-2}=1\]
oh ok yeah i made a table and i got those results, but i wasnt sure if there was a limit or not. i have to write why, but im not quite sure of the reason.
\[\lim_{x \rightarrow 2}\frac{|x-2|}{x-2} DNE\]
\[f(x) = \frac{|x-2|}{x-2} = \left\{\begin{array}{rcc} 1 & \text{if} & x \geq 2 \\ -1& \text{if} & x < 2 \end{array} \right.\]
tada!
do you know if we have |x|, then: x>0 => |x|=x x<0 => |x|=-x x=0 => |x|=0
why is it writing everything on one line :(
hmmm. ?
