Graph as shown below
Explanation:
The first thing we can do is simplify
We know
So hence
we know what
graph{y = 2^x [-10.085, 9.915, -1.44, 8.56]}
But
What is a stretch of
Hence we yield:
graph{2^(3x+1) [-10.21, 9.79, -1.52, 8.48]}
We can see from this graph that it has a domain of
We can also see that it has a range of:
It hence has a
