To evaluate the function [tex]\( f(x) = x - 3 \)[/tex] at [tex]\( x = 3 \)[/tex], follow these steps:
1. Start with the given function:
[tex]\[ f(x) = x - 3 \][/tex]
2. Substitute the value of [tex]\( x \)[/tex] with 3:
[tex]\[ f(3) = 3 - 3 \][/tex]
3. Simplify the expression:
[tex]\[ f(3) = 0 \][/tex]
Therefore, when [tex]\( x = 3 \)[/tex], the value of the function [tex]\( f(x) = x - 3 \)[/tex] is [tex]\( 0 \)[/tex].
