Answer 1

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

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

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

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

4. Now add \( 6 \) to \( 21 \): \[ 21 + 6 = 27 \]

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

Final Answer: \[ f(3) = 27 \]
