Question

If f(x) = 1-x which value is equivalent to |f(I)|

Answer 1

Answer:given that

F (x)=1-x

Explanation:

Answer 2

The value of |f(i)| is √2.

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)|=√((1)^2+(-1)^2)`
`[\because |a+ib|=√(a^2+b^2)]`

`|f(i)|=√(1+1)`

`|f(i)|=√(2)`

Therefore the value of |f(i)| is √2.
