1) As we have in this exponential function, a base such as 0
2) So, the end behavior can be described by:
[tex]\begin{gathered} x\rightarrow\infty f(x)\rightarrow\infty \\ x\rightarrow-\infty,\text{ f(x)}\rightarrow-\infty \end{gathered}[/tex]
As long as the values of x increase the value of f(x) increases up to the asymptote y=6, and as x goes negative the values of f(x), or y, decrease as well.
3) Hence, the answer is:
[tex]\begin{gathered} x\rightarrow\infty f(x)\rightarrow\infty \\ x\rightarrow-\infty,\text{ f(x)}\rightarrow-\infty \end{gathered}[/tex]
