HW for Dec. 14 (Tues)
1) Graph the quadratic function y = -4x^2 + 4x - 8 on an x-y coordinate, plane by hand. Label each point that you use to draw the curve. DO NOT simply sketch the graph you see after plugging the equation into a calculator.
[hint: first build an x-y table, using x = -3,-2,-1,0,1,2,3,]
2) Use the graph of the equation above to estimate where the function's x-intercepts are. (recall that this is where the function crosses the x axis)
3) Explain in your own words why the graph of a quadratic function containing an "x^2" term (like the one above) can never be a straight line.

In case you haven't noticed...
Those of you actually trying out the HW for our class may have noticed that I have not posted any new problems for this week (Dec. 6-10). The idea was to give the large number of students who have fallen behind an 'amnesty week'; a week that they can focus on making up any of the first 4 weeks of online problems.
There will be one more week of homework before the break, for the week of Dec. 13-17 -- so be sure to check back starting next Monday. Also, I will probably post some review problems as an extra credit HW assignment, for students that can put in the effort and do some extra practice over break.
