A function f(x) is said to have a removable discontinuity at a: = a if both of the following conditions hold: 1. f is either not defined or not continuous at a: = a. 2. f(a) could either be defined or redefined so that the new function is continuous at a: = a. Show that x2+12112+41 ifss6 has a removable discontinuity at a: 6 by (a) verifying (1) in the definition above, and then (b) verifying (2) in the definition above by determining a value of f(6) that would make f continuous at :2: = 6. f(6) 2C] would make f continuous at a: = 6. _ Now draw a graph of m). It's just a couple of parabolas
