Answer 1

Respuesta:( c ) If ã < to < 72 , then { < 2n } is increasing , { X2n + 1 } is decreasing , limn - 00 22n = 72 , and limn - 700 I2n + 1 = 71 . ( d ) If ū2 < xo < 00 , then { z2n } is decreasing , { 22n + 1 } is increasing , limn - 700 22n = and limn - Z2n + 1 = 21 ( e ) If xo = 71 , then 22n = ži , and 22n + 1 = 72 for n = 0 , 1 , . ... If 0 < u < ī and v > Z2 then f ( u ) > f ( īı ) = 72 and f ( u ) < $ ( 72 ) = 11 and so cases ( a ) and ( d ) are dual .
