Solution:
Given the model;
![f(x)=64(0.75)^x](https://img.qammunity.org/2023/formulas/mathematics/college/v6h8id6oqs4oyie7q17g102d0ew8wcrky5.png)
Thus, the variable, x, represents the number of times the ball bounces.
The variable, f(x), represents the height of the ball after x bounces.
The parameter, 64, represents the initial height of the ball.
The parameter, 0.75, represents the percentage of height left from each previous bounce.
