Answer
See the picture below.
Work Step by Step
The parent function is $f(x)=2^x$ (with red) the given function is $g(x)=2^{x-3}-1$ (with blue).
The parent function can be graphed by calculating a few coordinates and connecting them with a smooth curve:
$f(-2)=2^{-2}=(\frac{1}{4})$
$f(-1)=2^{-1}=(\frac{1}{2}$
$f(0)=2^0=1$
$f(1)=2^1=2$
$f(2)=2^2=4$
For every corresponding x-value the following equation is true: $f(x-3)-1=g(x)$
This means that the graph is translated 3 units to the right and 1 unit down
($g(x)$ involves a horizontal shift of 3 to the right and also a vertical shift of 1 downwards.).
First, the horizontal shift.
We only consider the g(x) function as $g'(x)=2^{x-3}$
For example if $f(0)=1$ in the original $f(x)$, this will be equal to $g'(3)=f(3-3)=f(0)=1$.
Here,$ f(0)=g'(3)$ also, $f(1)=g'(4)$
We can see that here, each point in the parent function was moved to the right by 3 units.
Second, we translate this $g'(x)$ function to get the originally given function.
Now, the following equation is true: $g'(x)-1=g(x)$ Every $g'(x)$ value will be decreased by 1.
For example if $g'(3)=1$, this will be translated as $g'(3)-1=1-1=0$.
We can see that here, the $g'(x)$ is greater than $g(x)$ for every corresponding x-value by 1.)
