There are lots of videos on YouTube on how to do it I’m not completely sure so I don’t want to tell you something false
The 1 represents the y intercept so a point is (0,1). To find other points, plug in values for x. For example, plus in x and you get a y value of 2. So just plot a number of points and then connect them with a curved line( called a parabola).
