To evaluate the function [tex]\( f(x) = |x - 3| \)[/tex] at [tex]\( x = 3 \)[/tex], we'll follow these steps:
1. Substitute [tex]\( x = 3 \)[/tex] into the function:
[tex]\[
f(3) = |3 - 3|
\][/tex]
2. Compute the expression inside the absolute value:
[tex]\[
3 - 3 = 0
\][/tex]
3. Apply the absolute value:
[tex]\[
|0| = 0
\][/tex]
So, [tex]\( f(3) = 0 \)[/tex].
