To find \( f(8) \) given the function \( f(x) = 2(x - 5) \), follow these steps:
1. Identify the given function:
[tex]\[
f(x) = 2(x - 5)
\][/tex]
2. Substitute \( x = 8 \) into the function:
[tex]\[
f(8) = 2(8 - 5)
\][/tex]
3. Perform the operation inside the parentheses first:
[tex]\[
8 - 5 = 3
\][/tex]
4. Now multiply the result by 2:
[tex]\[
2 \times 3 = 6
\][/tex]
Thus, \( f(8) = 6 \). Therefore, the correct answer is:
[tex]\[
6
\][/tex]
