Question

If f(x)=x^3-3x^2+3x-4 find f(2)+f(-2)+f(0)

Answer 1

Step-by-step explanation:

Answer 2

Answer:

The correct answer is - 20

Step-by-step explanation:

Given data   f(x) = x³ - 3x² + 3x - 4

here we need to find  f(2) + f(-2) + f(0)  

f (2) =  2³ - 3(2)² + 3(2) - 4 = 8 - 3(4) + 6 -4 = 8 -12 + 6 -4 =  -2    

f (-2) = (-2)³ - 3(-2)² + 3 (-2) - 4  = 8 - 3(4) - 6 - 4 = 8 - 12 - 6 -4 = -14  

f (0) = 0³ - 3 (0)² + 3(0) - 4  = 0 + 0 + 0 - 4 = - 4

f (2) + f(-2) +f (0)  = -2 - 14 - 4 = - 20
