Day 34: Nspired Rational Functions

20141016_12132220141016_121143

Another great day in Precalculus.  I am so blessed with students who are really interested in understanding the mathematics rather than just memorizing for the test!  I am in “teacher heaven.” Today I gave my students the conditions for a rational function: Given the following information, write the rational function that has zeros at x = 2, x = 3, and vertical asymptote at x = 5.  It has a removable discontinuity  at x = -1.    It has a horizontal  asymptote of y = -3.  I then had them submit their answers via a QuickPoll with the TI Navigator system.  Then we compared and listed all the answers that were unique.  And then they were to look at each one and talk about what they thought need to be “fixed.”  Great discourse and they didn’t even need me to call on them…lots of cross-class discussion.  Learn so much from “mistakes.”
