Answer:
C. x = 6
Step-by-step explanation:
6 + 4 = 10
[7×(-3)] × (-2)²
= (-21) × 4
= -84
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:
