Essential Understandings

Concrete:

• Make predictions based upon data presented in a line graph or table.
• Make predictions based on data represented in an exponential or logarithmic graph or table.
• Indicate the point on a graph that crosses the y-axis.
• Compare two rates of change on a graph.
• Compare two rates of change in a display.
• Describe the rate of change qualitatively (e.g., steep = rapid rate of change).

• 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 that a calculator log button uses base 10.
• Understand that a calculator ln button uses base e.
• Use a tool (graphing calculator, scientific calculator, etc..) to solve for exponent. For example: 69.18 = , log 69.18 = x. 1.84 = x
• Understand that the exponent represents a value on the x axis and the answers represent values on the y axis for an exponential function base 10 or e.
  
  
• Use a tool (graphing calculator, scientific calculator, etc..) to solve for exponent.
  For example:
  x=1.386
