Provide an appropriate response.Explain why 
= ?x? when k is even but 
= x when k is odd.
What will be an ideal response?
When k is even, 
represents a nonnegative number. When x is nonnegative, then 
represents x. When x is negative, then 
represents the opposite of x. In all cases, 
represents ?x? when k is even. When k is odd, the sign of 
is the same as the sign of x. Thus 
when k is odd.
