1. Understanding

The student was able to generate graphs without having to attend to the intermediate steps of creating a table.

2. CCSS Alignment 

This description and use of language was more robust here than in #1-5 and illustrates appropriate use of vocabulary, direction, and quantity.


Standard referenced:

HSF-BF.B.3: Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.

3. Comprehension & Application

SMP.6: Attend to precision.


The student attended to precision on graphing (scaling and plotting ordered pairs) and vocabulary (using “vertical” instead of “translation up”).
