Answer 1

Answer: On interval f(x) is increasing =  $( -\infty, -2)$

On interval f(x) is decreasing = $( -\infty, -2)$

Step-by-step explanation:

The given function: $f(x)=-(x+2)^2+4$

The graph of the function is attached below

In graph , function is increasing till point (-2,4) or x=-2 and then it is decreasing.

So f(x) is increasing in $( -\infty, -2)$ and decreasing in $(-2, \infty)$

So, On interval f(x) is increasing =  $( -\infty, -2)$

On interval f(x) is decreasing = $( -\infty, -2)$
