If f(x) = x^3 – 2x^2, which expression is equivalent to f(i)?

2 - i

Step-by-step explanation:

If  i  in the expression  f(i)  is an imaginary number, then

f(i) =  i^3  -  2 i^2  =  -i  - 2*(-1)  =  2 - i

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
