    Answer:

    The value of |f(i)| is √2.

    Step-by-step explanation:

    The given function is

    f(x)=1-x

    We need to find the value of |f(i)|.

    Substitute x=i in the given function.

    f(i)=1-i

    Taking modulus on both the sides.

    |f(i)|=|1-i|

    Using the formula for modulus of a complex number, we get

    |f(i)|=\sqrt{(1)^2+(-1)^2}           [\because |a+ib|=\sqrt{a^2+b^2}]

    |f(i)|=\sqrt{1+1}

    |f(i)|=\sqrt{2}

    Therefore the value of |f(i)| is √2.
