1. The problem statement, all variables and given/known data Prove that f(x) = 1/(x^2) is not continuous at x = 0 using the epsilon and delta definition of a limit 2. Relevant equations definition of discontinuity There exist epsilon > 0 such that for all delta > 0 there is an x such that |x-0| < delta but |1/(x^2)| >= Epsilon 3. The attempt at a solution I don't know how to go from here. Like how do i prove it? I don't understand!
