Scoring Rubric for Grade 10 Practice Test Session 1, Item #11 Scoring Guide: Score Description The student response demonstrates an exemplary understanding of the Functions concepts involved 4 in building new functions from existing functions. The student correctly compares transformations of a function, and then graphs the function over a different transformation. The student response demonstrates a good understanding of the Functions concepts involved in building new functions from existing functions. Although there is significant evidence that the 3 student was able to recognize and apply the concepts involved, some aspect of the response is flawed. As a result, the response merits 3 points. The student response demonstrates a fair understanding of the Functions concepts involved in 2 building new functions from existing functions. While some aspects of the task are completed correctly, others are not. The mixed evidence provided by the student merits 2 points. The student response demonstrates a minimal understanding of the Functions concepts involved in 1 building new functions from existing functions. The student response contains insufficient evidence of an understanding of the Functions concepts 0 involved in building new functions from existing functions to merit any points. Sample Response: A. 2 = 2, then 2+k = and = f(4) k B. −7; Since −5 −7. C. shifts up 3 units, where shifts left 3 units. f(x)+3 f(x) f(x+3) f(x) D.
