Answer:
<em>Neither Increasing or Decreasing </em>
<em>Increasing</em>

<em>Increasing</em>
<em>Neither Increasing or Decreasing </em>
Step-by-step explanation:
To know if the graph of a function is growing or decreasing you must use the graph to verify what happens when x increases.
If when x increases y decreases, then the function is decreasing.
If when x increases y increases, then the function is growing.
Let's look at the
<u>First interval.</u>
Note that the value of y is always equal in this interval, therefore the function <em>is not increasing or decreasing.</em>
<em />
<u>Second interval</u>
Note that when x increases from -12 to -10, the value of y increases from y = 1 to y = 3.
Then the function is increasing in this interval
<u>Third interval</u>
Note that when x = -9 y= 8, but when x approaches -6 then y approaches 7.
Therefore in this interval the function is decreasing.
<u>Fourth interval</u>
When x = -6 y = 7 and at the end of the interval when x = -4 then y = 11
The function is increasing.
<u>Fifth interval</u>
The value of y remains constant throughout the interval. So the function is <em>not increasing and it is not decreasing</em>
