Given:

There are given that the function:


f(x)=(1)/((x+3))-2

Step-by-step explanation:

The graph of the given function is shown below:

Now,

(1) Domain:

To find the domain of the given function, we need to find the value where the function is defined.

Then,

The domain of the given function is:


\text{Domain: (-}\infty,-3)\cup(-3,\infty)

(2) Range:

To find the range of the given function, we need to find the set of values that correspond with the domain.

So,

The range of the given function is:


(-\infty,-2)\cup(-2,\infty)

(3) Increasing on:


\text{ increasing on: never increasing}

(4) Decreasing on:

The value of decreasing on:


(-\infty,-3),(-3,\infty)

(5): All asymptote:

The value of asymptote are:


\begin{gathered} \text{vertical asymptote : x=-3} \\ \text{Horizontal asymptote : y=-2} \end{gathered}

(6) All limit (4):


\begin{gathered} f(x)=(1)/((x+3))-2 \\ f(4)=(1)/((4+3))-2 \\ f(4)=(1)/(7)-2 \\ f(4)=(-13)/(7) \end{gathered}

Hence, the all limit at 4 is -1.85.
