Answer:
8
Step-by-step explanation:
f(- 2) = 8
f(-2) = 2 (-2) ^ 4 - 4 (- 2) ^ 3 - 11 (- 2) ^ 2 + 3*(- 2) - 6 = 2 * 16 + 32 - 44 - 6 - 6 = 8
Therefore the value of f(x) is 8 at x = - 2
Answer:
f(- 2) = 8
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = 2
- 4(- 2)³ - 11(- 2)² +3(- 2) - 6
= 2(16) - 4(- 8) - 11(4) - 6 - 6
= 32 + 32 - 44 - 12
= 64 - 56
= 8
