Answer:

\sqrt{2}


Step-by-step explanation:

We plug in i into f(x) to get:

f(i)=1-i


<em>Here, i is the imaginary number i=\sqrt{-1}</em>

To get absolute value of an imaginary number, we use the following formula:

a+bi=\sqrt{a^2+b^2}


So absolute value of f(i) is:

|f(i)|=\sqrt{(1)^2+(1)^2} \\=\sqrt{1+1} \\=\sqrt{2}
