Answer:
a v-shaped graph with a minimum at (-2,-1) and x-intercepts at -1 and -3
Step-by-step explanation:
if you need to graph the function then start by creating an x-y table of values:
when x=0, y=1
so you the point: (0, 1)
when x=2, y=3
you have another point: (2,3)
when x=-2, y = -1
third point: (-2,-1)
when x=-3, y = 0
fourth point: (-3,0)

Step-by-step explanation:
Try to think of something that doesn't involve energy and you won't get very far. Even thinking—even thinking about energy!—needs some energy to make it happen. In fact, everything that happens in the world uses energy of one kind or another. But what exactly is energy?
Energy is a bit of a mystery. Most of the time we can't see it, yet it is everywhere around us. Revving car engines burn energy, hot cups of coffee hold energy, street lights that shine at night are using energy, sleeping dogs are using energy too—absolutely everything you can think of is using energy in one way or another. Energy is a magical thing that makes other things happen. Everything in the world is either energy or matter ("stuff" around us) and even matter, when you really get down to it, is a kind of energy!
