For f (x) = -2x^3-4x^2+3x-8, use the remainder theorem to determine f (-1).

Hello

- 13

Explanation step by step:

x = - 1

f (x) = remainder to be divided by (x + 1)

f ( - 1) = - 2 ( - 1) ³ - 4 ( - 1) ² + 3 ( - 1) - 8

= 2 - 4 - 3 - 8 = - 13

The rest of the division of f (x) / (x + 1) = - 13

- 13

Step-by-step explanation:

Substitute x = - 1 into f (x) to obtain the remainder on dividing by (x + 1)

f ( - 1) = - 2 ( - 1) ³ - 4 ( - 1) ² + 3 ( - 1) - 8

= 2 - 4 - 3 - 8 = - 13

Thus the remainder on dividing f (x) by (x + 1) is - 13
