Graphs (2007)

This Graphs (2007) assessment also includes:

Challenge the class to utilize their knowledge of linear and quadratic functions to determine the intersection of the parent quadratic graph and linear proportional graphs. Using the pattern for the solutions, individuals develop a general formula for them. Then, using algebraic methods, young mathematicians show their formulas hold true.

Instructional Ideas

  • Lead a discussion after the task about whether the general solution works if the slope of the linear function is negative
  • Use the assessment as a spring board into the discussion of HSA-REI.D.11, finding the solutions for f(x) = g(x)
Classroom Considerations

  • Learners should be familiar with working with quadratic equations
Pros

  • Contains sample work for various point values
  • Provides descriptions of misunderstandings based upon the tasks performance on a national math assessment
Cons

  • The mathematical symbols do not display correctly in the rubric
