Formally $lim\mathrm{????}\to \mathrm{????}\mathrm{????}(\mathrm{????})=\mathrm{????}$ means that given any $\mathrm{????}\mathrm{????}\mathrm{????}\mathrm{????}>0,$ there exists $\mathrm{????}>0$ such that for all $\mathrm{????}\ne \mathrm{????},$ if  then When demonstrating that $lim\mathrm{????}\to 5\mathrm{????}2-10\mathrm{????}=-25$ with $\mathrm{????}\mathrm{????}\mathrm{????}\mathrm{????}=0\mathrm{.}7,$ find the largest number $\mathrm{????}$ such thatif  then $\mathrm{????}=$

 

Formally lime f(x) = L means that given any > 0, there exists > 0 such that for all xc, if |xc|
