The decay factor of the exponential function given in the table is of
.
<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, we have that when x increases by 1, y decreases by a factor of 3, hence the decay rate r is found as follows:

Answer:
The fraction of the tank is filled with gasoline is
.
Step-by-step explanation:
Consider the provided information.
Jamal filled his gas tank and then use 7/16 of the tank for traveling to visit his grandfather.
After his first traveling the amount of gas left can be calculated as:



He then used 1/3 of the remaining gas in the tank to run around town.
That means he left with 2/3 of gas.


Hence, the fraction of the tank is filled with gasoline is
.
