A −4

B −3

C −1

D 4

Answer 1

None? Are you sure you copied the question right?

Explanation:

x^2 - 3x - 4 = | x+3 | -2

Substitute

(-4)^2 - 3(-4) - 4 = | (-4)+3 | -2

16 + 12 -4 = 1-2

Not equal

(−3)^2 - 3(−3) - 4 = | (−3)+3 | -2

9+9-4 = -2

Not equal

(−1)^2 - 3(−1) - 4 = | (−1)+3 | -2

1 -3 -4 = 2-2

Not equal

4^2 - 3(4) - 4 = | 4+3 | -2

16 - 12-4 = 7-2
