Solved Example on Quadratic Function
Graph the quadratic function
. Indicate whether the parabola opens up or down.
Choices:
A. Graph-A; opens down
B. Graph-B; opens down
Correct Answer: A
Solution:
Step 1: Make a table of ordered pairs for the given function.
Step 2: Plot these points on the coordinate plane and connect the points with a smooth curve.
Step 3: The graph looks like the one below:
Step 4: It can be observed from the graph that the parabola opens down.
Step 5: The equation of the axis of symmetry is: x = 0.
Step 6: The vertex is at (0, 0).
Step 7: The parabola opens down. So, the vertex is the maximum point.
