In a sample problem for scoring the CC Alg 1 regents (#3 in the link below), students are asked to graph y = abs(X + 1) and then asked the range of the function and the domain on which the graph is increasing. The scoring rubric gives x > -1 (open interval) as the correct increasing interval instead of x>= -1 (closed interval). The definition of increasing and decreasing and whether the intervals are open and closed are discussed every year on the AP Calculus listserv. The correct interval should be closed not open.
For someone who attended this session at the May NTI, did anyone raise an objection to the scoring rubric for this question? This type of question could easily be on the June 3rd exam.
One more example of why we need a statewide glossary.
