To find the total number of bounces Matt makes before shooting free throws, you can create an expression based on the information provided.
Since Matt bounces the ball 4 times before each free throw shot and he shot \( f \) free throws, the total number of bounces is calculated as follows:
\[ \text{Total bounces} = 4 \times f \]
So, the expression that shows the total number of bounces is \( 4f \).
