The exponential equation that correctly models the ball's peak height, h, in meters, after b bounces is given by:

<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem:
- Rocio drops a ball from a height of 4 meters, hence A(0) = 4.
- Each time the ball bounces, it reaches a peak height which is 79% of the previous peak height, hence 1 - r = 0.79.
Thus, the equation is given by:

I don't know this sorry is there any other way I could help you
B is the answer i had this on my test the other day
3^(-2) = 1/(3^2) = 1/(3*3) = 1/9
The rule used here is x^(-y) = 1/(x^y) to make the exponent positive.
3^2 turns into 3*3 because the exponent 2 tells us how many copies of the base '3' to multiply out.
