Unformatted text preview: 1, 2 ± ² ³ ´ . • We obtain a line segment . • 1 ( ) + 1 = 2 , so the left endpoint of this piece is at 1, 2 ( ) . • 2 ( ) + 1 = 3 , so the right endpoint of this piece is at 2, 3 ( ) . • Both 1 and 2 are included in the subdomain 1, 2 ± ² ³ ´ . Therefore, the endpoints 1, 2 ( ) and 2, 3 ( ) are included in this piece, and we plot them as filledin circles. The graph of f is below. In calculus , we say that f has a jump discontinuity at 1 x = 1 ( ) . (See Part G.) §...
