For any real number x, the operatoris defined as:
(x) = x(2 − x)
If p + 1 =(p + 1), then p =	Choose the correct choice from the following:  A) - 2  B) 0  C) 1  D) 2  E) 3

Rationale: ( x ) = x ( 2 − x ) ( p + 1 ) = ( p + 1 ) ( 2 - p - 1 ) = ( 1 - p ) ( p + 1 ) we are given that p + 1 = ( p + 1 ) therefore ( 1 - p ) ( p + 1 ) = ( p + 1 ) or ( p + 1 ) + ( p - 1 ) ( p + 1 ) = 0 ( p + 1 ) ( p - 1 ) = 0 p = - 1 , p = 1 option c
Answer: C
