I am having a real tough time understanding problems dealing with epsilon and delta, so I am just picking problems out of my book and trying to do them myself but don't have solutions to them, so if someone could help me with this problem it would be great....

I am to prove the statement using the epsilon, delta definition of limit

limit as x --> 3 for (x^2 + x - 4) = 8

and sorry i don't have it in math format how you guys can type it..
