Question

G(x) = x3 + 6x2 + 12x + 8



Determine the function’s value when x = −1.

Answer 1

g(-1) = 1

Explanation:

Synthetic division is by far the fastest way to evaluate this function at x = -1. Set up synth. div. as follows:

-1 ) 1 6 12 8

-1 -5 -7

----------------------

1 5 7 1

since the remainder is 1, g(-1) = 1
