What is the end behavior? 10 points!!

Given:
The given function is:
[tex]f_1(x)=-3\cdot 2^{x-5}-4[/tex]
The graph of the function is given.
To find:
The end behavior of the given function.
Solution:
We have,
[tex]f_1(x)=-3\cdot 2^{x-5}-4[/tex]
From the given graph it is clear that the function approaches to -4 at x approaches negative infinite and the function approaches to negative infinite at x approaches infinite.
[tex]f_1(x)\to -4[/tex] as [tex]x\to -\infty[/tex]
[tex]f_1(x)\to -\infty[/tex] as [tex]x\to \infty[/tex]
Therefore, the end behaviors of the given function are:
[tex]f_1(x)\to -4[/tex] as [tex]x\to -\infty[/tex]
[tex]f_1(x)\to -\infty[/tex] as [tex]x\to \infty[/tex]
