Answer:
1) For :
and
, 2) For
:
and
Step-by-step explanation:
The polynomial is a second-order polynomial of the form
. By direct comparison, we construct the following system of equations:
(1)
(2)
By (1) we know that there are a family of pairs such that the system of equations is satisfied. Let suppose that both and
are integers. We assume two arbitrary integers for
:
1)
2)
Using an exponential function, it is found that the value of Yong's investment account after 7 years is given by:
(C) $2363
<h3>What is an exponential function?</h3>It is modeled by:
In which:
Her account was worth $2000 initially, and it increases by 10%, percent every 4 years, hence, it is modeled by:
After 7 years, the amount is:
Hence option C is correct.
