To solve this problem you must apply the proccedure shown below: 1. You have to find the distance from the center to the focus, as below: c=√(a^2-b^2) Where a is the major radius and b is the minor radius. 2. Therefore, by the graph, you have: a=6 a^2=36 b=3 b^2=9 3. When you substitute the values, you obtain: c=5.2 4. As you can see in the graph, the coordinates of the center is (3,4), then, the locations of the foci: 3+c=8.2 3-c=-2.2 The answer is: (-2.2,4) and (8.2,4)
