The polynomial expression is 2x^3 - 3x - 4.

A. When x = 4, the expression becomes 2(4)^3 - 3(4) - 4 = 2(64) - 12 - 4 = 128 - 12 - 4 = 112.

B. When x = 0, the expression becomes 2(0)^3 - 3(0) - 4 = 0 - 0 - 4 = -4.

C. When x = 1, the expression becomes 2(1)^3 - 3(1) - 4 = 2(1) - 3 - 4 = 2 - 3 - 4 = -5.

Therefore, the values of the polynomial expression for the given values of x are:

* A. 112

* B. -4

* C. -5
