Whаt аre the sоlutiоns tо the system shown? A coordinаte plane with labeled x- and y-axes is shown. A gray circle is centered at the origin and intersects the x-axis at approximately (−4, 0) and (4, 0), and the y-axis at about (0, 4) and (0, −4). Two red curves appear on the left and right sides of the circle. Each red curve touches the circle at the points (−4, 0) and (4, 0), respectively, and then curves outward away from the circle as y increases or decreases. The red curves are symmetric across the x-axis and open away from the center horizontally.
