Look at the graph. Which describes an interval where the function is decreasing?
O 2 - < x < 2
000 O-2

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

its line 2 i just added the rest or else it wouldn't let me answer
