If you have the following function, f ( x ) = -x 2 - 5x + 4, compute f (3), f (-2), f (5), f (-4).
A. f (3) = 0, f (-2) = 21, f (5) = 6, f (-4) = 43
B. f (3) = –2, f (-2) = 18, f (5) = 4, f (-4) = 40
C. f (3) = 1, f (-2) = 20, f (5) = 7, f (-4) = 42
D. f (3) = –1, f (-2) = 19, f (5) = 5, f (-4) = 41
