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.
