So as you all know, you have a project due very soon over quadratic functions. Here is a cool video on some quadratic functions that some students put together.
Describe in your own words the differences between a linear function and a quadratic function. Give at least two differences.
Fill in the blank: You can use the __________ of a quadratic function to determine the equation's number and type of solutions.
Lastly, what would your quadratic function be given the zero's/roots x = 8 and x = -2?
I want you to use your critical thinking skills and what we have learned so far in class to figure this
out.
So now we are covering quadratic functions which as you all can see are very different from linear functions.
1. What is the standard form for a quadratic function? What is the vertex form for a quadratic function?
Watch the video below!
NOTE: When she says find the equation of the axis of symmetry all she means is find the axis of symmetry like we do in class.
2. What vertex did she obtain in the video? Was her vertex a maximum or minimum?
3. Did her graph open upwards or downwards? How do we in general determine whether a graph opens upward or downward?
4. Was her graph more narrow or wider than the parent graph y = f(x) ^2 ?
5. Lastly, in class on Friday bring in the completed example worked out on the video ( I want you to work the example yourself). You can choose to complete the problem the way she did or the way we learned in class ( you don't have to make a table).
You must complete each question in this discussion to obtain credit. No late submissions excepted. Due: Friday, March 8, 2012 @ 8:30am
