hi all, i'm working on some problems at calc on the web. The limit of x 2 as x approaches 2 is 4. That is, lim x -> 2 x 2 = 4 Let epsilon= 0.2. Find delta > 0 such that if | x - 2 | < delta then | x 2 - 4 | < 0.2 so far i've plugged f(x), L and epsilon into f(x)-L > epsilon to get: x 2 -4 < 1/5, and...
