Unformatted text preview: a f x ( ) exists, but 2) f is still discontinuous at a Then, the graph of f has a “hole” at the point a , lim x ± a f x ( ) ( ) . Example 3 (Revisiting Example 9 from Section 2.1) Let g x ( ) = x + 3, x ± 3 ( ) . (Figure 2.8.c) g has a removable discontinuity at 3, because: 1) lim x ± 3 g x ( ) = 6 , but 2) g is still discontinuous at 3; here, g 3 ( ) is undefined. The graph of g has a hole at the point 3, 6 ( ) ....
