I'm given the limit f(x + [tex]\Delta[/tex]x) / [tex]\Delta[/tex]x(adsbygoogle = window.adsbygoogle || []).push({});

Given f(x) is 2x + 3, do I just plug in 2x +3 into x? Or do I plug it into x and [tex]\Delta[/tex]x, or do I find the limits of f(x + [tex]\Delta[/tex]x) / [tex]\Delta[/tex]x) and -f(x)/[tex]\Delta[/tex]x?, etc..If someone could get me started on this it would be great, Thanks.
