For the limit
x → 2
(x^3 − 4x + 7) = 7
illustrate the definition by finding the largest possible values of δ that correspond to ε = 0.2 and ε = 0.1. (Round your answers to four decimal places.)...note:let d=delta, E=epsilon
0</x-a/<d, then /f(x)-L/<E
0</x-2/<d, then /x^3-4x/<E...
so taking the right part of the statement further:
I'm not sure what to do here. Even if I plug in E=0.2, I'm still left with the x's...please help me out, any advice/tips are appreciated.
