A function f has a removable discontinuity at x = c if limf(x) exists by f is not continuous at x = c, either because f is not defined at cor because the definition for f(c) differs from the value of the limit. A removable discontinuity at x = c can be "removed" by redefining the value of f at x = c. Find the values of x at which x - 2 f(x) = |x| – 2 is not continuous, and determine whether each value is a removable discontinuity. Give numeric answers in ascending order. X1 = is discontinuity. X2 = is discontinuity.
