If f(x) = 3x + 2, what is f(5)?

To find the value of f(5) for the function f(x) = 3x + 2, you need to substitute 5 in place of x in the equation. Here’s how to compute it step-by-step:

1. Start with the function: f(x) = 3x + 2.
2. Substitute 5 for x: f(5) = 3(5) + 2.
3. Multiplying 3 by 5 gives you 15: f(5) = 15 + 2.
4. Finally, add 2 to 15: f(5) = 17.

Thus, the value of f(5) is 17, confirming that the correct answer is indeed the choice representing 17. This demonstrates how to evaluate a linear function at a specific point by substituting the input value into the function’s formula.
