Use synthetic division and the Remainder Theorem to find the indicated function value.
-$$f ( x ) = 2 x ^ { 3 } - 7 x ^ { 2 } - 5 x + 12 ; f ( - 3 )$$
A) $- 90$
B) $- 18$
C) 54
D) $- 120$

Question

Quizplus · Accepted Answer

Using synthetic division with $x = -3$, the coefficients of $f(x) = 2x^3 - 7x^2 - 5x + 12$ are divided by -3. The remainder from this division is the value of $f(-3)$, which is $-90$.
