To find: The vertex, the axis of the symmetry and the
Answer to Problem 6E
The vertex is
Explanation of Solution
Given information:
The graph is shown in Figure 1.
Figure 1
The behavior of the graph of the parabola is U shaped curve where axis of symmetry can be drawn through the vertex of parabola.
It can be seen from the graph that it is form of the parabola whose vertex is
It can be seen from the graph that the axis of symmetry is the vertical line.
The vertical symmetry passes through the vertex
Therefore, the symmetrical axis is
The y -intercept is the point where the value of
It can be seen from the given graph parabola intersect the y-axis at point
Therefore, the y -intercept is
