A f The sketch shows a circle, a parabola, which is the graph of f, and a straight line, which is the graph of g. The parabola has r-intercepts -2 and 6, and y-intercept 6. Its turning point is C. The circle has its center at the origin and it passes through the point A, which has coordinates (-2,0). At point B both the circle and the straight line cut the r-axis. The straight line has y-intercept 1.
