If f(x) = 1 – x, which value is equivalent to |f(i)|?

a. 0
b. 1
c. √2
d. √-1

If you would like to know which value is equivalent to |f(i)|, you can calculate this using the following steps:

f(x) = 1 - x
|f(i)| = |1 - i| = sqrt((1-i) * (1-i)^conjugate) = sqrt(2) = √2

The correct result would be c. √2.

9/12 is the answer because 3/4 times 3 each is 9/12
