Answer 1

To find \( f(3) \) for the function \( f(x) = 5x + 6 \), you need to substitute \( x \) with 3 in the function.

\[
f(3) = 5(3) + 6
\]

Now, calculate it step by step:

1. First, multiply \( 5 \) by \( 3 \):
\[
5 \times 3 = 15
\]

2. Then, add \( 6 \) to the result:
\[
15 + 6 = 21
\]

So, \( f(3) = 21 \).

The answer is:
\[
f(3) = 21
\]
