1. CCSS Alignment
The table was not constructed to show exponential growth so there is no evidence of proficiency for standard HSF-LE.A.3.
HSF-LE.A.3: Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function.
The student appears to be able to reason from tables, but does not seem to be able to reason from the graph. However, there is evidence of improvement in attending to equal intervals in the graph when you compare this graph to the student’s work in task 4.1.
3. Comprehension & Application
SMP.7: Look for and make use of structure.
The structure of the graph does not follow convention because the student switches the independent and the dependent axes.
4. CCSS Alignment
The student is below proficiency in HSF-LE.B.5. The student is misinterpreting the parameters in the exponential function. The student is not recognizing that a percent growth factor is a parameter in an exponential function.
HSF-LE.B.5: Interpret the parameters in a linear or exponential function in terms of a context.
