A) Z + 1
B) Z/2+3
C) Z^4
D) Z – y
E) Z^11
We need to check each option here:   A. Z + 1   This will depend on the value of Z. Nothing can be said   B. Z/2+3   This will depend on the value of Z. Nothing can be said   C. Z^4   This will always be positive. Even powers of negative numbers are positive and odd powers are negative   D. Z – y   This will depend on the value of Z. Nothing can be said   E. Z^11   This will always be negative. Z^11ven powers of negative numbers are positive and odd powers are negative   Correct Option: Z^11
