$f (0) = 1$ $f(0)=1$

Explanation:

Given
$XXX f (x) = x^{2} - 2 x + 1$ $color(white)("XXX")f(color(red)(x))=color(red)(x)^2-2color(red)(x)+1$

To find $f (0)$ $f(color(blue)(0))$ replace $x$ $color(red)(x)$ with $0$ $color(blue)(0)$
$XXX f (0) = 0^{2} - 2 (0) + 1 = 1$ $color(white)("XXX")f(color(blue)(0))=color(blue)(0)^2-2(color(blue)(0))+1 =color(green)(1)$
