Sagot :

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]
