To evaluate the polynomial -3x^3 + 8x^2 - 4x - 6 for x = 4 and for x = -4, substitute the values of x into the polynomial expression and calculate the result.

For x = 4: -3(4)^3 + 8(4)^2 - 4(4) - 6 = -3(64) + 8(16) - 16 - 6 = -192 + 128 - 16 - 6 = -66

For x = -4: -3(-4)^3 + 8(-4)^2 - 4(-4) - 6 = -3(-64) + 8(16) + 16 - 6 = 192 + 128 + 16 - 6 = 330
