Question

If f(x) = x³-3 x² + 3x-4. Then, find
the value of f (2) + f (-2) + f(o)​

Answer 1

Step-by-step explanation:

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

= 8-3×4+9-4

= 5×4+5

= 20+5

= 25

Answer 2

Answer:

-36

Step-by-step explanation:

f(x) = x³-3 x² + 3x-4

put the value of f(2) in f(x)

f(2)

$2^{3} - 3(2)^{2} + 3(2) - 4\\8 - 12 + 6 - 4 \\f(2) = -2$

put the value of f(-2) in f(x)

f(-2)

$-2^{3} - 3(-2)^{2} + 3(-2) - 4\\-8 - 12 - 6 - 4 \\f(-2) = -30$

put the value of f(0) in f(x)

f(0)

$0^{3} - 3(0)^{2} + 3(0) - 4\\0 - 0 + 0- 4 \\f(0) = -4$

f (2) + f (-2) + f(o)​

(-2) + (-30) + (-4)

-2 - 30 - 4

-36
