The epicenter of an earthquake is the point on Earth’s surface directly above the earthquake’s origin. A seismograph can be used
to determine the distance to the epicenter of an earthquake. Seismographs are needed in three different places to locate an earthquake’s epicenter. Find the location of the earthquake’s epicenter if it is 3 miles away from A(2,3), 4 miles away from B(−5,3), and 5 miles away from C(−1,−2).

Well let's first graph the quadratic equation,
Look at the image below ↓
By looking at the image below we can tell that the graph touches the x axis 2 times at,
<u>(-1,0)</u>
<u>(1 1/3,0)</u>
<em />
<em>Thus,</em>
<em>the parabola touches the x axis twice.</em>
