Answer :

Given the second function

the decreasing interval is given by

[tex](-2,2)[/tex]

the funtion

[tex]-5\left|x+1\right|+10[/tex]

have the following graph

then the decreasing interval of function 1 is

[tex](-1,\infty)[/tex]

the intersection of

[tex](-2,2)\cap(-1,\infty)[/tex][tex](-2,2)\cap(-1,\infty)=(-1,2)[/tex]

then the graph interval is
