Evaluate f (x) = 2x4 – 4x3 – 11x2 3x – 6 for x = –2. f (–2) =

Answer 1

Hello,

After decrypting the question:

f(x)=2x^4-4x^3-11x^2+3x-6

f(-2)=2(-2)^4-4(-2)^3-11(-2)^2+3*(-2)-6=2*16+32-44-6-6=8

Answer 2

Answer:

The value of f(x) is 8 at x=-2.

Step-by-step explanation:

The given function is

$f(x)=2x^4-4x^3-11x^2+3x-6$

We have to find the value of function at x=-2.

Substitute x=-2 in the given function.

$f(-2)=2(-2)^4-4(-2)^3-11(-2)^2+3(-2)-6$

$f(-2)=32+32-44-6-6$

$f(-2)=64-56$

$f(-2)=8$

Therefore the value of f(x) is 8 at x=-2.
