Answer 1

To find \( f(3) \) for the function \( f(x) = 7x + 6 \), we will substitute \( x = 3 \) into the function. Here are the steps:

1. Start with the function:
   \[ f(x) = 7x + 6 \]

2. Substitute \( x = 3 \):
   \[ f(3) = 7(3) + 6 \]

3. Calculate \( 7(3) \):
   \[ 7 \times 3 = 21 \]

4. Now, add 6 to this result:
   \[ f(3) = 21 + 6 \]

5. Finally, calculate the sum:
   \[ f(3) = 27 \]

So, \( f(3) = 27 \).
