SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given function.


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

STEP 2: Explain the means to use to find the required values

Since we were given a graph and can not use a caculator, we will be using the graph to get the values.

STEP 3: Plot the given function on a graph

STEP 4: Get the domain of the function

Domain: The domain is all x-values or inputs of a function. The domain of a graph consists of all the input values shown on the x-axis.


\begin{gathered} The\text{ domain from the graph is given as:} \\ x<-3\text{ or }x>-3 \\ \text{The interval notation is given as:} \\ (-\infty,-3)\cup(-3,\infty) \end{gathered}

STEP 5: Get the Range of the function

The range is all y-values or outputs of a function.


\begin{gathered} \mathrm{The\: set\: of\: values\: of\: the\: dependent\: variable\: for\: which\: a\: function\: is\: defined} \\ \text{The range of the graph is given as:} \\ f(x)<-2\text{ or }f(x)>-2 \\ \text{The interval notation is given as:} \\ (-\infty,-2)\cup(-2,\infty) \end{gathered}

STEP 6: Get the value on which the function is increasing on


\begin{gathered} \mathrm{If}\: f\: ^(\prime)\mleft(x\mright)>0\: \mathrm{then}\: f\mleft(x\mright)\: \mathrm{is\: increasing.} \\ \mathrm{If}\: f\: ^(\prime)\mleft(x\mright)<0\: \mathrm{then}\: f\mleft(x\mright)\: \mathrm{is\: decreasing.} \end{gathered}

STEP 7: Get the value on which the function is decreasing on


\begin{gathered} \mathrm{If}\: f\: ^(\prime)\mleft(x\mright)<0\: \mathrm{then}\: f\mleft(x\mright)\: \mathrm{is\: decreasing.} \\ It\text{ can be s}een\text{ that the function on the graph decreases on the point betw}een\text{ negative infinity} \\ \text{and -3 and the point betw}een\text{ -3 and infinity. }\therefore This\text{ can be written as:} \\ \: \\ \mathrm{Decreasing}\colon-\infty\: <p><strong>STEP 8: Get the values of the asymptotes</strong></p><p><strong>An asymptote is a line that a graph approaches without touching. Similarly, horizontal asymptotes occur because y can come close to a value, but can never equal that value. In the previous graph, there is no value of x for which y = 0 ( ≠ 0), but as x gets very large or very small, y comes close to 0.</strong></p>[tex]\mathrm{Vertical}\colon\: x=-3,\: \mathrm{Horizontal}\colon\: y=-2
