Concept explainers
The graph of each function and the axis of symmetry and vertex labelled on graph.
Answer to Problem 21PPE
Equation of axis of symmetry:
Explanation of Solution
Given:
The given function is:
Calculation:
Compare the given function with
Therefore, the axis of symmetry is:
The x-coordinate of the given function is
Finding the other two points on the graph of the given function:
Now, graph the vertex (3.33, -33.33) on the graph and with the other two points (0,0) and (1, -17).
Reflect the points across the axis of symmetry to get two more points on the graph.
Finally, connect these points to the parabola.
The graph will be:
