zero from your eyes replace x by 2

then see if this one exists \[\lim_{x \rightarrow 2^{}}\sqrt{x2}\]

no because the domain of \(\sqrt{x2}\) is \(x\geq 2\) so you cannot replace x by values less than 2

well, for 2+, limit exists. put just replace the x=2+ (since we do not have to overcome any indeterminant form) now 2+ is basically a no. a very wee bit larger than 2. that is about... "2.000000...001" so square root of (0.0000000...0001) is almost negligible, that is zero. So, '0'.

LHL of 2+ is 2. RHL is a wee bit more that 2.000...001, you can say 2.000....002

so when 2 isnt coming into the picture, so we don't have a prob there with domain or what lies under the square root. You're welcome

In the second problem, Limit doesnt exist, exactly for the same reasons that they do in the first problem

nope, limit can't be possibly one. there may have been a printing or typing error, not necessarily your prof's fault.
