If $f ( x ) = - 4 x ^ { 2 } + 6 x - 7$ , use synthetic division to evaluate f (2).
A) $f ( 2 ) = - 11$
B) $f ( 2 ) = 21$
C) $f ( 2 ) = - 35$
D) $f ( 2 ) = - 3$
E) $f ( 2 ) = - 1$

To evaluate $f(2)$ using synthetic division, we substitute $x = 2$ into the given function: $f(2) = -4(2)^2 + 6(2) - 7 = -4(4) + 12 - 7 = -16 + 12 - 7 = -11$.

If f(x)=−4x2+6x−7f ( x ) = - 4 x ^ { 2 } + 6 x - 7f(x)=−4x2+6x−7
