If f(x) = 1 – x, which value is equivalent to |f(i)|?
0
1
StartRoot 2 EndRoot
StartRoot negative 1 EndRoot

Replace x with i

f(i) = 1-i

Because i is in the formula, it is a complex number with a real number = 1 and an imaginary number = -1

The modulus of f(i) = |1-i| =

sqrt[1^2+(-1)^2] = sqrt(2)

The answer would be: StartRoot 2 EndRoot
