A function f(a) 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 a = a. 1 /00 + -7x+32 if x * 0, 4 Let f(ac) 19, if x = 0 Show that f(a) has a removable discontinuity at a = 0 and determine what value for f(0) would make f(a) continuous at a = 0. Must redefine f(0) = Hint: Try combining the fractions and simplifying. The discontinuity at a = 4 is not a removable discontinuity, just in case you were wondering
