Essential Understandings

Concrete:

• Make predictions based upon data presented in a line graph or table.
• Make predictions based on data represented in an exponential graph or table.
• Indicate the point on a graph that crosses the y-axis.
• Compare two rates of change on a graph.

• Use a template to compare function models with standard logarithmic functions. For example: Use the graph of a function to determine which of the functions below best models the given function.
  
  
  
  

• Understand the concepts and vocabulary: function, exponent, logarithm, growth, decay, base, model, graph.
• Understand that a logarithm ask the question “What exponent produced this answer?” The base of the exponent becomes the base of the log. The answer to the exponential function becomes a part of the log. The exponent becomes the answer to the logarithmic function.
  
  
• Use a template to create a function model for a given logarithm.
