To solve for [tex]\( f(3) \)[/tex] given the function [tex]\( f(x) = x^2 \)[/tex], we need to substitute [tex]\( x = 3 \)[/tex] into the function.
First, write down the function:
[tex]\[ f(x) = x^2 \][/tex]
Now, substitute [tex]\( x = 3 \)[/tex] into the function:
[tex]\[ f(3) = 3^2 \][/tex]
Calculate the square of 3:
[tex]\[ 3^2 = 9 \][/tex]
So, [tex]\( f(3) = 9 \)[/tex].
Therefore, the correct answer is:
[tex]\[ f(3) = 9 \][/tex]
This matches the provided options, confirming that the correct answer is:
[tex]\[ \boxed{9} \][/tex]
