A function f (x) is said to have a removable discontinuity at x = a if: 1. f is either not defined or not continuous at x = a. 2. fa) could either be defined or redefined so that the new function IS continuous at x = a. 2x2+ 4x - 48 Let f(a) = x - 4 Show that f() has a removable discontinuity at a = 4 and determine what value for f (4) would make f(a) continuous at x = 4. Must define f(4)
