Precalc 11 Week 9
This week in math 11 we did lots of review for our test coming up on November .
This week we did some word problems related to quadratics. I found these somewhat challenging and so I’m hoping we don’t have too many on the unit test. I do think I have a better understanding of parabolas now then I ever did. I have almost memorized every equation and how to get to it. I am very good with standard form and I am most comfortable changing general form into standard form. I can change factored to general and standard to general, it just takes me more time then using general to standard.
general to standard :
if you haveĀ y = + 12x + 32
y = ( + 12x + 36) +32 – 36
y = (x + 6 – 4
