Here you will begin you webquest for quadratic functions. When it says stop one, you will read the question and click on the link for Stop One to the right. You will also need to write down each answer for each question on a piece of paper. First you will need to write down the question for each part before clicking on the link.
Stop One: When will you use quadratic functions in the real world? Explore these pictures to find out just one example.
1. Name three bridges that would involve the quadratic function and why?
Stop Two: Let's explore the quadratic function.
1. Click on stop two and begin to explore the applet by moving the arrows up and down and watching the graph.
2. When you move the a coeffiecient (the first one), what happens to the graph?
3. When you move the b coeffiecient (the second one), what happens to the graph?
4. When you move the c coeffiecient (the third one), what happens to the graph?
5. Write down a general statement that will explain what each coeffient does.
Stop Three: Graphing Quadratic Functions: Here we will follow a power point created by C Leckie. DO NOT PRESS ANY KEY UNTIL THE END OF EACH PAGE! It is a timed power point.
1. When will the parabola open up?
2. When will the parabola open down?
3. What is the standard form of a quadratic function?
4. What is the equation for the line of symmetry?
5. The line of symmetry always goes through the __________________.
6. The line of symmetry gives us which coordinate for the vertex?
7. How do we find the y coordinate?
8. What are the three steps to graphing a parabola in standard form?
9. Write down each step to graphing the last example.
