Certainly! Let's find the value of [tex]\( f(4) \)[/tex] for the function [tex]\( f(x) \)[/tex].

The function is given by:
[tex]\[ f(x) = 2x - 3 \][/tex]

To find [tex]\( f(4) \)[/tex], we need to substitute [tex]\( x = 4 \)[/tex] into the function and evaluate it:
[tex]\[ f(4) = 2(4) - 3 \][/tex]

Now, let's perform the calculations step by step:

1. Multiply [tex]\( 2 \)[/tex] by [tex]\( 4 \)[/tex]:
[tex]\[ 2 \cdot 4 = 8 \][/tex]

2. Subtract [tex]\( 3 \)[/tex] from [tex]\( 8 \)[/tex]:
[tex]\[ 8 - 3 = 5 \][/tex]

So, the value of [tex]\( f(4) \)[/tex] is:
[tex]\[ f(4) = 5 \][/tex]

Therefore, the correct answer is:
A) 5
