<h2>Writing an Exponential Function given the Table</h2><h3>
Answer:</h3>
![y = 0.1(4)^x](https://tex.z-dn.net/?f=y%20%3D%200.1%284%29%5Ex)
<h3>
Step-by-step explanation:</h3>
Given:
![&x &y \\ &0 &0.1 \\ &1 &0.4 \\ &2 &1.6 \\ &3 &6.4](https://tex.z-dn.net/?f=%26x%20%26y%20%5C%5C%20%260%20%260.1%20%5C%5C%20%261%20%260.4%20%5C%5C%20%262%20%261.6%20%5C%5C%20%263%20%266.4)
The most basic form to write an exponential function is
. Where
is
when
. We can see from the given Table of Values that at
,
. So,
. The
is the common ratio and can be calculated by
, where
is
when
.
Solving for the Common Ratio:
![r = \frac{y_{n}}{y_{n-1}} \\ r = \frac{y_2}{y_{2-1}} \\ r = \frac{y_2}{y_1} \\r = \frac{1.6}{0.4} \\ r = 4](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7By_%7Bn%7D%7D%7By_%7Bn-1%7D%7D%20%5C%5C%20r%20%3D%20%5Cfrac%7By_2%7D%7By_%7B2-1%7D%7D%20%5C%5C%20r%20%3D%20%5Cfrac%7By_2%7D%7By_1%7D%20%5C%5Cr%20%3D%20%5Cfrac%7B1.6%7D%7B0.4%7D%20%5C%5C%20r%20%3D%204)
Now we know what
and
are. We can finally write the equation of the exponential function depicted by the table.
The equation is ![y = 0.1(4)^x](https://tex.z-dn.net/?f=y%20%3D%200.1%284%29%5Ex)
