associated with a parabola such as Axis of Symmetry, Vertex, Focus, Directrix, Quadratic Equation, Points, and Locus. For this lesson though, the following terms are important to understand: vertex, axis of symmetry, and range. As shown in Figure 1, the vertex of a parabola represents the high point of the tennis ball flight. As the name implies, suspension bridges, like the Golden Gate Bridge or Brooklyn Bridge, suspend the roadway by cables, ropes or chains from two tall towers. These towers support the majority of the weight as compression pushes down on the suspension bridge's deck and then travels up the cables, ropes or chains to transfer compression to the towers. method for drawing a parabola. It tells us exactly how we have to weight a chain so that it will hang in the form of a parabola. The key is that the weight distribution has to be uniform in the horizontal direction. For this reason, it is usually stated that the cables on a suspension bridge will hang in the shape of a parabola, since the weight
