    [tex]\sqrt{4x+1} < \frac{x-2}{2} < \delta[/tex]

    O wait, last post I assumed the //'s were your grouping symbols. I think theyre absolulote value signs >.<

    [tex]|\sqrt{4x+1}| < \frac{|x-2|}{2} < \delta[/tex]

    I hope thats what you want.

    This is the second time you have posted this. Thanks to Gib Z for writing out the formula (you forgot the second "|" on the square root). But I still have no idea what "2 is x and 3 is y, 3 goes to 3.5 and 2.5" could mean! 3 doesn't "go" anywhere- it just sits there! And there is no "y" in your expression.
