Answer:[tex]\begin{gathered} D=(-\infty,\infty) \\ \\ R=(-\infty,-3)\cup\lbrack-\frac{9}{4},\infty) \end{gathered}[/tex]
Explanation:
The domain of the given piecewise function are all the values that x can take.
These are:
x < -4 and
[tex]x\ge-4[/tex]
It can be written as:
[tex](-\infty,\infty)[/tex]
The range is:
[tex](-\infty,-3)\cup\lbrack-\frac{9}{4},\infty)[/tex]
