You have now been introduced to a number of additional function families that may be used to model real-world data.  You have also begun to analyze when each function family may be an appropriate choice for a data set.  Before proceeding to the next lesson, complete the lesson reflection.

Algebra II Journal: Reflection 3

Respond to the following reflection questions in your Algebra II Journal opens in new window and submit to your teacher.

Select one of the new function families to research in more depth:
  • Cubic Functions
  • Quartic Functions
  • Power Functions
  • Logarithmic Functions
  • Logistic Functions
  • Trigonometric Functions

For the function family you selected, use your textbook and online searches to develop a deeper understanding of the function family.  Summarize your findings and submit to your teacher.  Make sure to address the following:

  • Determine the key features of this function family.  (end behavior, number of possible maximum and minimum values, increasing/decreasing trends, etc.)
  • Include sample graphs to represent the variety of functions within this function family.
  • Include any possible contextual examples that could be modeled with this function type.
