Unformatted text preview: points. The current problem: To graph , we first find the vertex. As explained above, the value of the vertex is such that , and so . To obtain the value of the vertex, we evaluate at : Figure 1 . So the vertex of the graph occurs at . Next we find a point on the graph on each side of the vertex. For , we have . So the point is on the graph. For , we have . So the point is also on the graph. Drawing rays from the vertex through the points and , we obtain the graph of . Note that when drawing these graphs, it is very important that we do not extend the rays below the vertex . For additional explanation, see your textbook: • Section 2.2: Graphs of Functions...
