A function f () is said to have a removable discontinuity at x = a if: 1. f is either not defined or not continuous at x = a. 2. f(a) could either be defined or redefined so that the new function IS continuous at x = a. 2x2 + 6x - 8 Let f (ac) = x- 1 Show that f(x) has a removable discontinuity at a = 1 and determine what value for f(1) would make f(x) continuous at x = 1. Must define f(1) =
