Answer
The values are $\{1111.1,333.3,100,30,9,2.7\}$.
Range is decreasing.
Work Step by Step
The given function is
$y=100\cdot 0.3^x$
Substitute the values $x=\{-2,-1,0,1,2,3\}$
For $x=-2$.
$\Rightarrow y=100\cdot 0.3^{(-2)}$
$\Rightarrow y=\frac{100}{0.3^2}$
$\Rightarrow y=\frac{100}{0.09}$
$\Rightarrow y=1111.1$
For $x=-1$.
$\Rightarrow y=100\cdot 0.3^{(-1)}$
$\Rightarrow y=\frac{100}{0.3^1}$
$\Rightarrow y=\frac{100}{0.3}$
$\Rightarrow y=333.3$
For $x=0$.
$\Rightarrow y=100\cdot 0.3^{(0)}$
$\Rightarrow y=100\cdot 1$
$\Rightarrow y=100$
For $x=1$.
$\Rightarrow y=100\cdot 0.3^{(1)}$
$\Rightarrow y=100\cdot 0.3$
$\Rightarrow y=30$
For $x=2$.
$\Rightarrow y=100\cdot 0.3^{(2)}$
$\Rightarrow y=100\cdot 0.09$
$\Rightarrow y=9$
For $x=3$.
$\Rightarrow y=100\cdot 0.3^{(3)}$
$\Rightarrow y=100\cdot 0.027$
$\Rightarrow y=2.7$
