Response:


Sagot :

To determine the value of \( f(5) \) for the function \( f(x) = 3x + 2 \), follow these steps:

1. Identify the given function:
\( f(x) = 3x + 2 \).

2. Substitute \( x \) with 5:
[tex]\[ f(5) = 3(5) + 2 \][/tex]

3. Perform the multiplication:
[tex]\[ 3 \times 5 = 15 \][/tex]

4. Add the constant term:
[tex]\[ 15 + 2 = 17 \][/tex]

Thus, the value of \( f(5) \) is \( 17 \).

The correct answer is:
[tex]\[ \boxed{17} \][/tex]
