Solution Steps

Step 1: Substitute the value into the function

Substitute \( x = 3 \) into the function \( f(x) = 5x + 6 \): \[ f(3) = 5(3) + 6 \]

Step 2: Perform the multiplication

Multiply \( 5 \) by \( 3 \): \[ f(3) = 15 + 6 \]

Step 3: Add the numbers

Add \( 15 \) and \( 6 \): \[ f(3) = 21 \]

\(\square\)

Final Answer

\(\boxed{21}\)
