Finding a factorization for f(x) - L in epsilon-delta proof

[nameVoid]

Homework Statement

im not seeing a factorization for f(x)-L<e and and not sure how to proceed in this case

In fact, 7 is not the limit, so you're going to have a really tough time proving the limit you showed.

not too sure what you're trying to do, any more info?

my mistake that's limit x -> 1 5x^2+2x-13=7

 

[lanedance]

that one doesn't work either...

nameVoid, where are you getting these problems? Are you just making them up?
