Someone please help.
I am trying to prove the following two problems using the epsilon delta method: (|f(x) - L| < ∈ if 0 < |x - a| < δ)...
1.
The text arbitrarily allows δ = 1/6 and arrives at an answer of δ = min{1/6, ∈/18}. I've done the work but can't arrive at this answer, can someone help?
2.
I don't know how to manipulate |SQRT(x)-2| into the form of |x-4| (< δ) AND arrive at the book's answer; δ = 2∈.
Please help!
