Required:
We want to find the domain, interval and also graph the given function,
also identify that the given function is constant or not
Step-by-step explanation:
The graph of the given function is as below
The given function is constant
Domain of function is
![\left(-\infty \:,\:\infty \:\right)](https://img.qammunity.org/2023/formulas/mathematics/high-school/w20wyr90dr9bjnnq9k9p7gew4o30qu7fuh.png)
range of function is
![-1](https://img.qammunity.org/2023/formulas/mathematics/high-school/juitznsfb5exs563s68p9iua6499ov40kk.png)
Final answer:
