Answer:
Explanation:
I'll tell you how to do it, but I can't do it for you, sorry. I can't mark the graph.
You make an x and y chart and under x, you write 2,1,0,-1,-2.
You plug it into the equation to get what y equals. Then, you use them as coordinates and plug it into the graph. When you graph all of them, you should see some sort of a 'U' shape. And then you connect the dots on the graph using lines.
