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.

Standard form of a quadratic equation is y=ax2+bx+c. Vertex form for a quadratic equation is y=A(x-h)+k.the vertex she used was (1,6) and it was at maximum value.her graph open downward we determine that if the a is less than 0 or greater than.her graph was wider because a was less than 0.
ReplyDeletestandard former is y=ax^2+bx+c
ReplyDeleteVertex is usually y=a(x-h)+k
She'd used (1,6) and had a down graph
She determined whether the graph was greater than or less than 0. It was less than 0
