A function f(x) is said to have a removable discontinuity at x=a if: 1. ff 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. Let f(x)=2x^2+2x40/x4 Show that f(x) has a removable discontinuity at x=4 and determine what value for f(4) would make f(x) continuous at x=4 Must define f(4)=
